-  Release 18
-
-  
-   Release date:
-   2025-??-??, CURRENT AS OF 2025-06-20
-  
-
-  
-   Overview
-
-   
-    PostgreSQL 18 contains many new features
-    and enhancements, including:
-   
-
-   
-
-    
-     
-      (to be completed)
-     
-    
-   
-
-   
-    The above items and other new features of
-    PostgreSQL 18 are explained in more detail
-    in the sections below.
-   
-
-  
-
-  
-
-   Migration to Version 18
-
-   
-    A dump/restore using  or use of
-     or logical replication is required for
-    those wishing to migrate data from any previous release.  See 
-    linkend="upgrading"/> for general information on migrating to new
-    major releases.
-   
-
-   
-    Version 18 contains a number of changes that may affect compatibility
-    with previous releases.  Observe the following incompatibilities:
-   
-
-   
-
-
-
-    
-    
-    Change  default to enable data checksums
-    (Greg Sabino Mullane)
-    §
-    
-
-    
-    Checksums can be disabled with the
-    new initdb option
-    --no-data-checksums.  
-    requires matching cluster checksum settings, so this new option can
-    be useful to upgrade non-checksum old clusters.
-    
-    
-
-
-
-    
-    
-    Change time zone abbreviation handling (Tom Lane)
-    §
-    
-
-    
-    The system will now favor the current session's time
-    zone abbreviations before checking the server variable
-    . Previously
-    timezone_abbreviations was checked first.
-    
-    
-
-
-
-    
-    
-    Deprecate MD5 password
-    authentication (Nathan Bossart)
-    §
-    
-
-    
-    Support for MD5 passwords will be removed in a future major
-    version release.   and 
-    linkend="sql-alterrole"/> now emit deprecation warnings when
-    setting MD5 passwords.  These warnings can be disabled by setting
-    the  parameter to
-    off.
-    
-    
-
-
-
-    
-    
-    Change  and 
-    to process the inheritance children of a parent (Michael Harris)
-    §
-    
-
-    
-    The previous behavior can be performed by using the new
-    ONLY option.
-    
-    
-
-
-
-    
-    
-    Prevent COPY FROM
-    from treating \. as an end-of-file marker when
-    reading CSV files (Daniel Vérité, Tom Lane)
-    §
-    §
-    
-
-    
-     will still treat
-    \. as an end-of-file marker when reading
-    CSV files from STDIN.
-    Older psql clients connecting to
-    PostgreSQL 18 servers might experience 
-    linkend="app-psql-meta-commands-copy">\copy
-    problems.  This release also enforces that \.
-    must appear alone on a line.
-    
-    
-
-
-
-    
-    
-    Disallow unlogged partitioned tables (Michael Paquier)
-    §
-    
-
-    
-    Previously ALTER TABLE SET
-    [UN]LOGGED did nothing, and the creation of an
-    unlogged partitioned table did not cause its children to be unlogged.
-    
-    
-
-
-
-    
-    
-    Execute AFTER 
-    linkend="triggers">triggers as the role that was active when
-    trigger events were queued (Laurenz Albe)
-    §
-    
-
-    
-    Previously such triggers were run as the role that was active at
-    trigger execution time (e.g., at ).
-    This is significant for cases where the role is changed between queue
-    time and transaction commit.
-    
-    
-
-
-
-    
-    
-    Remove non-functional support for rule privileges in 
-    linkend="sql-grant"/>/ (Fujii Masao)
-    §
-    
-
-    
-    These have been non-functional since
-    PostgreSQL 8.2.
-    
-    
-
-
-
-    
-    
-    Remove column 
-    linkend="view-pg-backend-memory-contexts">pg_backend_memory_contexts.parent
-    (Melih Mutlu)
-    §
-    
-
-    
-    This is no longer needed since
-    pg_backend_memory_contexts.path
-    was added.
-    
-    
-
-
-
-    
-    
-    Change
-    pg_backend_memory_contexts.level
-    and 
-    linkend="functions-admin-signal-table">pg_log_backend_memory_contexts()
-    to be one-based (Melih Mutlu, Atsushi Torikoshi, David Rowley,
-    Fujii Masao)
-    §
-    §
-    §
-    
-
-    
-    These were previously zero-based.
-    
-    
-
-   
-
-  
-
-  
-   Changes
-
-    
-     Below you will find a detailed account of the changes between
-    PostgreSQL 18 and the previous major
-    release.
-    
-
-   
-    Server
-
-    
-     Optimizer
-
-     
-
-
-
-      
-      
-      Automatically remove some unnecessary table self-joins (Andrey
-      Lepikhov, Alexander Kuzmenkov, Alexander Korotkov, Alena Rybakina)
-      §
-      
-
-      
-      This optimization can be disabled using server variable 
-      linkend="guc-enable-self-join-elimination"/>.
-      
-      
-
-
-
-      
-      
-      Convert some 
-      linkend="functions-comparisons-in-scalar">IN (VALUES
-      ...) to x = ANY ... for better
-      optimizer statistics (Alena Rybakina, Andrei Lepikhov)
-      §
-      
-      
-
-
-
-      
-      
-      Allow transforming 
-      linkend="functions-logical">OR-clauses
-      to arrays for faster index processing (Alexander Korotkov, Andrey
-      Lepikhov)
-      §
-      
-      
-
-
-
-      
-      
-      Speed up the processing of 
-      linkend="sql-intersect">INTERSECT,
-      EXCEPT, 
-      linkend="tutorial-window">window aggregates, and 
-      linkend="sql-createview">view column aliases (Tom Lane,
-      David Rowley)
-      §
-      §
-      §
-      §
-      
-      
-
-
-
-      
-      
-      Allow the keys of SELECT
-      DISTINCT to be internally reordered to avoid sorting
-      (Richard Guo)
-      §
-      
-
-      
-      This optimization can be disabled using 
-      linkend="guc-enable-distinct-reordering"/>.
-      
-      
-
-
-
-      
-      
-      Ignore GROUP BY
-      columns that are functionally dependent on other columns (Zhang
-      Mingli, Jian He, David Rowley)
-      §
-      
-
-      
-      If a GROUP BY clause includes all columns of
-      a unique index, as well as other columns of the same table, those
-      other columns are redundant and can be dropped from the grouping.
-      This was already true for non-deferred primary keys.
-      
-      
-
-
-
-      
-      
-      Allow some 
-      linkend="sql-having">HAVING clauses
-      on GROUPING
-      SETS to be pushed to 
-      linkend="sql-where">WHERE clauses
-      (Richard Guo)
-      §
-      §
-      §
-      §
-      
-
-      
-      This allows earlier row filtering.  This release also fixes some
-      GROUPING SETS queries that used to return
-      incorrect results.
-      
-      
-
-
-
-      
-      
-      Improve row estimates for 
-      linkend="functions-srf-series">generate_series()
-      using numeric
-      and timestamp
-      values (David Rowley, Song Jinzhou)
-      §
-      §
-      
-      
-
-
-
-      
-      
-      Allow the optimizer to use Right Semi Join plans
-      (Richard Guo)
-      §
-      
-
-      
-      Semi-joins are used when needing to find if there is at least
-      one match.
-      
-      
-
-
-
-      
-      
-      Allow merge joins to use 
-      linkend="guc-enable-incremental-sort">incremental sorts
-      (Richard Guo)
-      §
-      
-      
-
-
-
-      
-      
-      Improve the efficiency of planning queries accessing many partitions
-      (Ashutosh Bapat, Yuya Watari, David Rowley)
-      §
-      §
-      
-      
-
-
-
-      
-      
-      Allow partitionwise
-      joins in more cases, and reduce its memory usage (Richard Guo,
-      Tom Lane, Ashutosh Bapat)
-      §
-      §
-      
-      
-
-
-
-      
-      
-      Improve cost estimates of partition queries (Nikita Malakhov,
-      Andrei Lepikhov)
-      §
-      
-      
-
-
-
-      
-      
-      Improve SQL-language
-      function plan caching (Alexander Pyhalov, Tom Lane)
-      §
-      §
-      
-      
-
-
-
-      
-      
-      Improve handling of disabled optimizer features (Robert Haas)
-      §

-    
-     Indexes
-
-     
-
-
-
-      
-      
-      Allow skip scans of btree indexes
-      (Peter Geoghegan)
-      §
-      §
-      
-
-      
-      This allows multi-column btree indexes to be used by queries that
-      only equality-reference the second or later indexed columns.
-      
-      
-
-
-
-      
-      
-      Allow non-btree unique indexes to be used as partition keys and in
-      materialized views (Mark Dilger)
-      §
-      §
-      
-
-      
-      The index type must still support equality.
-      
-      
-
-
-
-      
-      
-      Allow GIN indexes to
-      be created in parallel (Tomas Vondra, Matthias van de Meent)

-    
-     General Performance
-
-     
-
-
-
-      
-      
-      Add an asynchronous I/O subsystem (Andres Freund, Thomas Munro,
-      Nazir Bilal Yavuz, Melanie Plageman)
-      §
-      §
-      §
-      §

-      §
-      §
-      §
-      §
-      
-
-      
-      This feature allows backends to queue multiple read requests,
-      which allows for more efficient sequential scans, bitmap
-      heap scans, vacuums, etc.  This is enabled by server
-      variable , with server
-      variables  and 
-      linkend="guc-io-max-combine-limit"/> added to control it.
-      This also enables 
-      and 
-      values greater than zero for systems without
-      fadvise() support.  The new system view 
-      linkend="view-pg-aios">pg_aios
-      shows the file handles being used for asynchronous I/O.
-      
-      
-
-
-
-      
-      
-      Improve the locking performance of queries that access many relations
-      (Tomas Vondra)
-      §
-      
-      
-
-
-
-      
-      
-      Improve the performance and reduce memory usage of hash joins and
-      GROUP BY
-      (David Rowley, Jeff Davis)
-      §
-      §
-      §
-      §
-      §
-      
-
-      
-      This also improves hash set operations used by 
-      linkend="sql-except">EXCEPT, and hash
-      lookups of subplan values.
-      
-      
-
-
-
-      
-      
-      Allow normal vacuums to freeze some pages, even though they are
-      all-visible (Melanie Plageman)
-      §
-      §
-      
-
-      
-      This reduces the overhead of later full-relation
-      freezing.  The aggressiveness of this can be
-      controlled by server variable and per-table setting 
-      linkend="guc-vacuum-max-eager-freeze-failure-rate"/>.  Previously
-      vacuum never processed all-visible pages until freezing was required.
-      
-      
-
-
-
-      
-      
-      Add server variable  to control
-      file truncation during  (Nathan Bossart,
-      Gurjeet Singh)
-      §
-      
-
-      
-      A storage-level parameter with the same name and behavior already
-      existed.
-      
-      
-
-
-
-      
-      
-      Increase server variables 
-      linkend="guc-effective-io-concurrency"/>'s and 
-      linkend="guc-maintenance-io-concurrency"/>'s default values to 16
-      (Melanie Plageman)
-      §
-      §
-      
-
-      
-      This more accurately reflects modern hardware.

-      
-      Increase the logging granularity of server variable 
-      linkend="guc-log-connections"/> (Melanie Plageman)
-      §
-      
-
-      
-      This server variable was previously only boolean, which is still
-      supported.
-      
-      
-
-
-
-      
-      
-      Add log_connections option to report the duration
-      of connection stages (Melanie Plageman)
-      §
-      
-      
-
-
-
-      
-      
-      Add  escape
-      %L to output the client IP
-      address (Greg Sabino Mullane)
-      §
-      
-      
-
-
-
-      
-      
-      Add server variable  to log
-      lock acquisition failures (Yuki Seino, Fujii Masao)
-      §
-      §
-      
-
