Release 9.2.22
+
+
+
Release date:
+
+
+ This release contains a variety of fixes from 9.2.21.
+ For information about new features in the 9.2 major release, see
+ .
+
+
+ The
PostgreSQL community will stop releasing updates+ for the 9.2.X release series in September 2017.
+ Users are encouraged to update to a newer release branch soon.
+
+
+
+
Migration to Version 9.2.22
+
+ A dump/restore is not required for those running 9.2.X.
+
+
+ However, if you are upgrading from a version earlier than 9.2.20,

Changes
+
+
+
+
+ On Windows, retry process creation if we fail to reserve the address
+ range for our shared memory in the new process (Tom Lane, Amit
+ Kapila)
+
+
+ This is expected to fix infrequent child-process-launch failures that
+ are probably due to interference from antivirus products.
+
+
+
+
+ Fix low-probability corruption of shared predicate-lock hash table
+ in Windows builds (Thomas Munro, Tom Lane)
+
+
+
+
+ Avoid logging clean closure of an SSL connection as though
+ it were a connection reset (Michael Paquier)
+
+
+
+
+ Prevent sending SSL session tickets to clients (Tom Lane)
+
+
+ This fix prevents reconnection failures with ticket-aware client-side
+ SSL code.
+
+
+
+
+ Fix code for setting on
+ Solaris (Tom Lane)
+
+
+
+
+ Fix statistics collector to honor inquiry messages issued just after
+ a postmaster shutdown and immediate restart (Tom Lane)
+
+
+ Statistics inquiries issued within half a second of the previous
+ postmaster shutdown were effectively ignored.
+
+
+
+
+ Ensure that the statistics collector's receive buffer size is at
+ least 100KB (Tom Lane)
+
+
+ This reduces the risk of dropped statistics data on older platforms
+ whose default receive buffer size is less than that.
+
+
+
+
+ Fix possible creation of an invalid WAL segment when a standby is
+ promoted just after it processes an XLOG_SWITCH WAL
+ record (Andres Freund)
+
+
+
+
+ Fix SIGHUP and SIGUSR1 handling in
+ walsender processes (Petr Jelinek, Andres Freund)
+
+
+
+
+ Fix unnecessarily slow restarts of
walreceiver+ processes due to race condition in postmaster (Tom Lane)
+
+
+
+
+ Fix cases where an INSERT or UPDATE assigns
+ to more than one element of a column that is of domain-over-array
+ type (Tom Lane)
+
+
+
+
+ Move autogenerated array types out of the way during
+ ALTER ... RENAME (Vik Fearing)
+
+
+ Previously, we would rename a conflicting autogenerated array type
+ out of the way during CREATE; this fix extends that
+ behavior to renaming operations.
+
+
+
+
+ Ensure that ALTER USER ... SET accepts all the syntax
+ variants that ALTER ROLE ... SET does (Peter Eisentraut)
+
+
+
+
+ Properly update dependency info when changing a datatype I/O
+ function's argument or return type from opaque to the
+ correct type (Heikki Linnakangas)
+
+
+ CREATE TYPE updates I/O functions declared in this
+ long-obsolete style, but it forgot to record a dependency on the
+ type, allowing a subsequent DROP TYPE to leave broken
+ function definitions behind.
+
+
+
+
+ Reduce memory usage when ANALYZE processes
+ a tsvector column (Heikki Linnakangas)
+
+
+
+
+ Fix unnecessary precision loss and sloppy rounding when multiplying
+ or dividing money values by integers or floats (Tom Lane)
+
+
+
+
+ Tighten checks for whitespace in functions that parse identifiers,
+ such as regprocedurein() (Tom Lane)
+
+
+ Depending on the prevailing locale, these functions could
+ misinterpret fragments of multibyte characters as whitespace.
+
+
+
+
+ Use relevant #define symbols from Perl while
+ compiling
PL/Perl (Ashutosh Sharma, Tom Lane)+
+
+ This avoids portability problems, typically manifesting as
+ a handshake mismatch during library load, when working with
+ recent Perl versions.
+
+
+
+
+ In
psql, fix failure when COPY FROM STDIN+ is ended with a keyboard EOF signal and then another COPY
+ FROM STDIN is attempted (Thomas Munro)
+
+
+ This misbehavior was observed on BSD-derived platforms (including
+ macOS), but not on most others.
+
+
+
+
+ Fix
pg_dump to not emit invalid SQL for an empty+ operator class (Daniel Gustafsson)
+
+
+
+
+ Fix
pg_dump output to stdout on Windows (Kuntal Ghosh)+
+
+ A compressed plain-text dump written to stdout would contain corrupt
+ data due to failure to put the file descriptor into binary mode.
+
+
+
+
+ Fix pg_get_ruledef() to print correct output for
+ the ON SELECT rule of a view whose columns have been
+ renamed (Tom Lane)
+
+
+ In some corner cases,
pg_dump relies+ on pg_get_ruledef() to dump views, so that this error
+ could result in dump/reload failures.
+
+
+
+
+ Fix dumping of function expressions in the FROM clause in
+ cases where the expression does not deparse into something that looks
+ like a function call (Tom Lane)
+
+
+
+
+ Fix
pg_basebackup output to stdout on Windows+ (Haribabu Kommi)
+
+
+ A backup written to stdout would contain corrupt data due to failure
+ to put the file descriptor into binary mode.
+
+
+
+
+ Fix
pg_upgrade to ensure that the ending WAL record+ does not have = minimum
+ (Bruce Momjian)
+
+
+ This condition could prevent upgraded standby servers from
+ reconnecting.
+
+
+
+
+ Always use
+ shared libraries with gcc (Tom Lane)
+
+
+ This supports larger extension libraries on platforms where it makes
+ a difference.
+
+
+
+
+ Fix unescaped-braces issue in our build scripts for Microsoft MSVC,
+ to avoid a warning or error from recent Perl versions (Andrew
+ Dunstan)
+
+
+
+
+ In MSVC builds, handle the case where the
openssl+ library is not within a VC subdirectory (Andrew Dunstan)
+
+
+
+
+ In MSVC builds, add proper include path for
libxml2+ header files (Andrew Dunstan)
+
+
+ This fixes a former need to move things around in standard Windows
+ installations of
libxml2.+
+
+
+
+ In MSVC builds, recognize a Tcl library that is
+ named tcl86.lib (Noah Misch)
+
+
+
+
+
+

+
Release 9.3.18
+
+
+
Release date:
+
+
+ This release contains a variety of fixes from 9.3.17.
+ For information about new features in the 9.3 major release, see

+
+
+
+
Migration to Version 9.3.18
+
+ A dump/restore is not required for those running 9.3.X.
+
+
+ However, if you are upgrading from a version earlier than 9.3.16,
+ see .
+
+
+
+
+
+
Changes
+
+
+
+
+ Fix concurrent locking of tuple update chains (Álvaro Herrera)
+
+
+ If several sessions concurrently lock a tuple update chain with
+ nonconflicting lock modes using an old snapshot, and they all
+ succeed, it was possible for some of them to nonetheless fail (and
+ conclude there is no live tuple version) due to a race condition.
+ This had consequences such as foreign-key checks failing to see a
+ tuple that definitely exists but is being updated concurrently.
+
+
+
+
+ Fix potential data corruption when freezing a tuple whose XMAX is a
+ multixact with exactly one still-interesting member (Teodor Sigaev)
+
+
+
+
+ On Windows, retry process creation if we fail to reserve the address
+ range for our shared memory in the new process (Tom Lane, Amit
+ Kapila)
+
+
+ This is expected to fix infrequent child-process-launch failures that
+ are probably due to interference from antivirus products.

+
+
+
+
+ Fix unnecessarily slow restarts of
walreceiver+ processes due to race condition in postmaster (Tom Lane)
+
+
+
+
+ Fix cases where an INSERT or UPDATE assigns
+ to more than one element of a column that is of domain-over-array
+ type (Tom Lane)
+
+
+
+
+ Allow window functions to be used in sub-SELECTs that
+ are within the arguments of an aggregate function (Tom Lane)
+
+
+
+
+ Move autogenerated array types out of the way during
+ ALTER ... RENAME (Vik Fearing)
+
+
+ Previously, we would rename a conflicting autogenerated array type
+ out of the way during CREATE; this fix extends that

+
+
+
+

PL/Perl (Ashutosh Sharma, Tom Lane)+
+
+ This avoids portability problems, typically manifesting as
+ a handshake mismatch during library load, when working with
+ recent Perl versions.
+
+
+
+
+ In
libpq, reset GSS/SASL and SSPI authentication+ state properly after a failed connection attempt (Michael Paquier)
+
+
+ Failure to do this meant that when falling back from SSL to non-SSL
+ connections, a GSS/SASL failure in the SSL attempt would always cause
+ the non-SSL attempt to fail. SSPI did not fail, but it leaked memory.
+
+
+
+
+ In
psql, fix failure when COPY FROM STDIN+ is ended with a keyboard EOF signal and then another COPY
+ FROM STDIN is attempted (Thomas Munro)
+
+
+ This misbehavior was observed on BSD-derived platforms (including
+ macOS), but not on most others.
+
+
+
+
+ Fix
pg_dump and pg_restore to+ emit REFRESH MATERIALIZED VIEW commands last (Tom Lane)
+
+
+ This prevents errors during dump/restore when a materialized view
+ refers to tables owned by a different user.
+
+
+
+
+ Fix
pg_dump with the + drop event triggers as expected (Tom Lane)
+
+
+ It also now correctly assigns ownership of event triggers; before,
+ they were restored as being owned by the superuser running the
+ restore script.
+
+
+
+
+ Fix
pg_dump to not emit invalid SQL for an empty+ operator class (Daniel Gustafsson)
+
+
+
+
+ Fix
pg_dump output to stdout on Windows (Kuntal Ghosh)+
+
+ A compressed plain-text dump written to stdout would contain corrupt
+ data due to failure to put the file descriptor into binary mode.
+
+
+

+ the ON SELECT rule of a view whose columns have been
+ renamed (Tom Lane)
+
+
+ In some corner cases,
pg_dump relies+ on pg_get_ruledef() to dump views, so that this error
+ could result in dump/reload failures.
+
+
+
+
+ Fix dumping of outer joins with empty constraints, such as the result
+ of a NATURAL LEFT JOIN with no common columns (Tom Lane)
+
+
+
+
+ Fix dumping of function expressions in the FROM clause in
+ cases where the expression does not deparse into something that looks
+ like a function call (Tom Lane)
+
+
+
+
+ Fix
pg_basebackup output to stdout on Windows+ (Haribabu Kommi)
+
+
+ A backup written to stdout would contain corrupt data due to failure
+ to put the file descriptor into binary mode.
+
+
+
+
+ Fix
pg_upgrade to ensure that the ending WAL record+ does not have = minimum
+ (Bruce Momjian)
+
+
+ This condition could prevent upgraded standby servers from
+ reconnecting.
+
+
+
+
+ In postgres_fdw, re-establish connections to remote
+ servers after ALTER SERVER or ALTER USER
+ MAPPING commands (Kyotaro Horiguchi)
+
+
+ This ensures that option changes affecting connection parameters will
+ be applied promptly.
+
+
+
+
+ In postgres_fdw, allow cancellation of remote
+ transaction control commands (Robert Haas, Rafia Sabih)
+
+
+ This change allows us to quickly escape a wait for an unresponsive
+ remote server in many more cases than previously.
+
+
+
+
+ Always use
+ shared libraries with gcc (Tom Lane)
+
+
+ This supports larger extension libraries on platforms where it makes
+ a difference.
+
+
+
+
+ Fix unescaped-braces issue in our build scripts for Microsoft MSVC,
+ to avoid a warning or error from recent Perl versions (Andrew
+ Dunstan)
