Changes
+
+
+
+
+
+ Fix failure of ALTER TABLE ... ALTER COLUMN TYPE
+ when altering multiple columns' types in one command (Tom Lane)
+
+
+ This fixes a regression introduced in the most recent minor releases:
+ indexes using the altered columns were not processed correctly,
+ leading to strange failures during ALTER TABLE.
+
+
+
+
+
+ Install dependencies to prevent dropping partition key columns
+ (Tom Lane)
+
+
+ ALTER TABLE ... DROP COLUMN will refuse to drop
+ a column that is a partition key column. However, indirect drops
+ (such as a cascade from dropping a key column's data type) had no
+ such check, allowing the deletion of a key column. This resulted in
+ a badly broken partitioned table that could neither be accessed nor
+ dropped.
+
+
+ This fix adds pg_depend entries that
+ enforce that the whole partitioned table, not just the key column,
+ will be dropped if a cascaded drop forces removal of the key column.
+ However, such entries will only be created when a partitioned table
+ is created; so this fix does not remove the risk for pre-existing
+ partitioned tables. The issue can only arise for partition key
+ columns of non-built-in data types, so it seems not to be a hazard
+ for most users.
+
+
+
+
+
+ Don't optimize away GROUP BY columns when the
+ table involved is an inheritance parent (David Rowley)
+
+
+ Normally, if a table's primary key column(s) are included
+ in GROUP BY, it's safe to drop any other grouping
+ columns, since the primary key columns are enough to make the groups
+ unique. This rule does not work if the query is also reading
+ inheritance child tables, though; the parent's uniqueness does not
+ extend to the children.
+
+
+
+
+
+ Avoid using unnecessary sort steps for some queries
+ with GROUPING SETS (Andrew Gierth, Richard Guo)
+
+
+
+
+
+ Fix failure to access trigger transition tables
+ during EvalPlanQual rechecks (Alex Aktsipetrov)
+
+
+ Triggers that rely on transition tables sometimes failed in the
+ presence of concurrent updates.
+
+
+
+
+
+ Fix mishandling of multi-column foreign keys when rebuilding a
+ foreign key constraint (Tom Lane)
+
+
+ ALTER TABLE could make an incorrect decision about
+ whether revalidation of a foreign key is necessary, if not all
+ columns of the key are of the same type. It seems likely that the
+ error would always have been in the conservative direction, that is
+ revalidating unnecessarily.
+
+
+
+
+
+ Don't build extended statistics for inheritance trees (Tomas Vondra)
+
+
+ This avoids a tuple already updated by self
error
+ during ANALYZE.
+
+
+
+
+
+ Avoid spurious deadlock errors when upgrading a tuple lock
+ (Oleksii Kliukin)
+
+
+ When two or more transactions are waiting for a transaction T1 to
+ release a tuple-level lock, and T1 upgrades its lock to a higher
+ level, a spurious deadlock among the waiting transactions could be
+ reported when T1 finishes.
+
+
+
+
+
+ Fix failure to resolve deadlocks involving multiple parallel worker
+ processes (Rui Hai Jiang)
+
+
+ It is not clear whether this bug is reachable with non-artificial
+ queries, but if it did happen, the queries involved in an
+ otherwise-resolvable deadlock would block until canceled.
+
+
+
+
+
+ Prevent incorrect canonicalization of date ranges
+ with infinity endpoints (Laurenz Albe)
+
+
+ It's incorrect to try to convert an open range to a closed one or
+ vice versa by incrementing or decrementing the endpoint value, if
+ the endpoint is infinite; so leave the range alone in such cases.
+
+
+
+
+
+ Fix loss of fractional digits when converting very
+ large money values to numeric (Tom Lane)
+
+
+
+
+
+ Fix spinlock assembly code for MIPS CPUs so that it works on
+ MIPS r6 (YunQiang Su)
+
+
+
+
+
+ Make
libpq ignore carriage return
+ (\r) in connection service files
+ (Tom Lane, Michael Paquier)
+
+
+ In some corner cases, service files containing Windows-style
+ newlines could be mis-parsed, resulting in connection failures.
+
+
+
+
+
+ In
psql, avoid offering incorrect tab
+ completion options
+ after SET variable =
+ (Tom Lane)
+
+
+
+
+
+ Fix a small memory leak in
psql's
+ \d command (Tom Lane)
+
+
+
+
+
+ Fix
pg_dump to ensure that custom operator
+ classes are dumped in the right order (Tom Lane)
+
+
+ If a user-defined opclass is the subtype opclass of a user-defined
+ range type, related objects were dumped in the wrong order,
+ producing an unrestorable dump. (The underlying failure to handle
+ opclass dependencies might manifest in other cases too, but this is
+ the only known case.)
+
+
+
+
+
+ Fix possible lockup in
pgbench when
+ using option (Fabien Coelho)
+
+
+
+
+
+ Fix contrib/passwordcheck to coexist with other
+ users of check_password_hook (Michael Paquier)
+
+
+
+
+
+ Fix contrib/sepgsql tests to work under recent
+ SELinux releases (Mike Palmiotto)
+
+
+
+
+
+ Improve stability of src/test/recovery
+ regression tests (Michael Paquier)
+
+
+
+
+
+ Reduce stderr output
+ from
pg_upgrade's test script (Tom Lane)
+
+
+
+
+
+ Fix TAP tests to work with msys Perl, in cases where the build
+ directory is on a non-root msys mount point (Noah Misch)
+
+
+
+
+
+ Support building Postgres with Microsoft Visual Studio 2019
+ (Haribabu Kommi)
+
+
+
+
+
+ In Visual Studio builds, honor WindowsSDKVersion
+ environment variable, if that's set (Peifeng Qiu)
+
+
+ This fixes build failures in some configurations.
+
+
+
+
+
+ Support OpenSSL 1.1.0 and newer in Visual Studio builds
+ (Juan José Santamaría Flecha, Michael Paquier)
+
+
+
+
+
+ Allow
make options to be passed down
+ to
gmake when non-GNU make is invoked at
+ the top level (Thomas Munro)
+
+
+
+
+
+ Avoid choosing localtime
+ or posixrules as TimeZone
+ during
initdb (Tom Lane)
+
+
+ In some cases
initdb would choose one of
+ these artificial zone names over the real
zone name.
+ Prefer any other match to the C library's timezone behavior over
+ these two.
+
+
+
+
+
+ Adjust pg_timezone_names view to show
+ the Factory time zone if and only if it has a
+ short abbreviation (Tom Lane)
+
+
+ Historically, IANA set up this artificial zone with
+ an abbreviation
like Local time zone must be
+ set--see zic manual page. Modern versions of the tzdb
+ database show -00 instead, but some platforms
+ alter the data to show one or another of the historical phrases.
+ Show this zone only if it uses the modern abbreviation.
+
+
+
+
+
+ Sync our copy of the timezone library with IANA tzcode release 2019b
+ (Tom Lane)
+
+
+ This adds support for
zic's new
+ slim option to reduce the size of the installed zone files.
+ We are not currently using that, but may enable it in future.
+
+
+
+
+
+ Update time zone data files to
tzdata+ release 2019b for DST law changes in Brazil, plus
+ historical corrections for Hong Kong, Italy, and Palestine.
