+ Release 9.3.23
+
+
+ Release date:
+ 2018-05-10
+
+
+
+ This release contains a variety of fixes from 9.3.22.
+ For information about new features in the 9.3 major release, see
+ .
+
+
+
+ Migration to Version 9.3.23
+
+
+ A dump/restore is not required for those running 9.3.X.
+
+
+
+ However, if the function marking mistakes mentioned in the first
+ changelog entry below affect you, you will want to take steps to
+ correct your database catalogs.
+
+
+
+ Also, if you are upgrading from a version earlier than 9.3.22,

+
+
+
+
+ Changes
+
+
+
+
+
+ Fix incorrect volatility markings on a few built-in functions
+ (Thomas Munro, Tom Lane)
+
+
+
+ The functions
+ query_to_xml,
+ cursor_to_xml,
+ cursor_to_xmlschema,
+ query_to_xmlschema, and
+ query_to_xml_and_xmlschema
+ should be marked volatile because they execute user-supplied queries
+ that might contain volatile operations. They were not, leading to a
+ risk of incorrect query optimization. This has been repaired for new
+ installations by correcting the initial catalog data, but existing
+ installations will continue to contain the incorrect markings.
+ Practical use of these functions seems to pose little hazard, but in
+ case of trouble, it can be fixed by manually updating these
+ functions' pg_proc entries. (Note that that
+ will need to be done in each database of the installation.) Another
+ option is to pg_upgrade the database to a
+ version containing the corrected initial data.
+
+
+
+
+
+ Avoid re-using TOAST value OIDs that match dead-but-not-yet-vacuumed
+ TOAST entries (Pavan Deolasee)
+
+
+
+ Once the OID counter has wrapped around, it's possible to assign a
+ TOAST value whose OID matches a previously deleted entry in the same
+ TOAST table. If that entry were not yet vacuumed away, this resulted
+ in unexpected chunk number 0 (expected 1) for toast
+ value nnnnn
errors, which would
+ persist until the dead entry was removed
+ by VACUUM. Fix by not selecting such OIDs when
+ creating a new TOAST entry.
+
+
+
+
+
+ Change ANALYZE's algorithm for updating
+ pg_class.reltuples
+ (David Gould)
+
+
+
+ Previously, pages not actually scanned by ANALYZE
+ were assumed to retain their old tuple density. In a large table
+ where ANALYZE samples only a small fraction of the
+ pages, this meant that the overall tuple density estimate could not
+ change very much, so that reltuples would
+ change nearly proportionally to changes in the table's physical size
+ (relpages) regardless of what was actually
+ happening in the table. This has been observed to result
+ in reltuples becoming so much larger than
+ reality as to effectively shut off autovacuuming. To fix, assume
+ that ANALYZE's sample is a statistically unbiased
+ sample of the table (as it should be), and just extrapolate the
+ density observed within those pages to the whole table.
+
+
+
+
+
+ Fix UPDATE/DELETE ... WHERE CURRENT OF to not fail
+ when the referenced cursor uses an index-only-scan plan (Yugo Nagata,
+ Tom Lane)
+
+
+
+
+
+ Fix incorrect planning of join clauses pushed into parameterized
+ paths (Andrew Gierth, Tom Lane)
+
+
+
+ This error could result in misclassifying a condition as
+ a join filter
for an outer join when it should be a
+ plain filter
condition, leading to incorrect join
+ output.
+
+
+
+
+
+ Fix misoptimization of CHECK constraints having
+ provably-NULL subclauses of
+ top-level AND/OR conditions
+ (Tom Lane, Dean Rasheed)
+
+
+
+ This could, for example, allow constraint exclusion to exclude a
+ child table that should not be excluded from a query.
+
+
+
+
+
+ Avoid failure if a query-cancel or session-termination interrupt
+ occurs while committing a prepared transaction (Stas Kelvich)
+
+
+
+
+
+ Fix query-lifespan memory leakage in repeatedly executed hash joins
+ (Tom Lane)
+
+
+
+
+
+ Fix overly strict sanity check
+ in heap_prepare_freeze_tuple
+ (Álvaro Herrera)
+
+
+
+ This could result in incorrect cannot freeze committed
+ xmax
failures in databases that have
+ been pg_upgrade'd from 9.2 or earlier.
+
+
+
+
+
+ Prevent dangling-pointer dereference when a C-coded before-update row
+ trigger returns the old
tuple (Rushabh Lathia)
+
+
+
+
+
+ Reduce locking during autovacuum worker scheduling (Jeff Janes)
+
+
+
+ The previous behavior caused drastic loss of potential worker
+ concurrency in databases with many tables.
+
+
+
+
+
+ Ensure client hostname is copied while copying
+ pg_stat_activity data to local memory
+ (Edmund Horner)
+
+
+
+ Previously the supposedly-local snapshot contained a pointer into
+ shared memory, allowing the client hostname column to change
+ unexpectedly if any existing session disconnected.
+
+
+
+
+
+ Fix incorrect processing of multiple compound affixes
+ in ispell dictionaries (Arthur Zakirov)
+
+
+
+
+
+ Fix collation-aware searches (that is, indexscans using inequality
+ operators) in SP-GiST indexes on text columns (Tom Lane)
+
+
+
+ Such searches would return the wrong set of rows in most non-C
+ locales.
+
+
+
+
+
+ Count the number of index tuples correctly during initial build of an
+ SP-GiST index (Tomas Vondra)
+
+
+
+ Previously, the tuple count was reported to be the same as that of
+ the underlying table, which is wrong if the index is partial.
+
+
+
+
+
+ Count the number of index tuples correctly during vacuuming of a
+ GiST index (Andrey Borodin)
+
+
+
+ Previously it reported the estimated number of heap tuples,
+ which might be inaccurate, and is certainly wrong if the
+ index is partial.
+
+
+
+
+
+ Allow scalarltsel
+ and scalargtsel to be used on non-core datatypes
+ (Tomas Vondra)
+
+
+
+
+
+ Reduce libpq's memory consumption when a
+ server error is reported after a large amount of query output has
+ been collected (Tom Lane)
+
+
+
+ Discard the previous output before, not after, processing the error
+ message. On some platforms, notably Linux, this can make a
+ difference in the application's subsequent memory footprint.
+
+
+
+
+
+ Fix double-free crashes in ecpg
+ (Patrick Krecker, Jeevan Ladhe)
+
+
+
+
+
+ Fix ecpg to handle long long
+ int variables correctly in MSVC builds (Michael Meskes,
+ Andrew Gierth)
+
+
+
+
+
+ Fix mis-quoting of values for list-valued GUC variables in dumps
+ (Michael Paquier, Tom Lane)
+
+
+
+ The local_preload_libraries,
+ session_preload_libraries,
+ shared_preload_libraries,
+ and temp_tablespaces variables were not correctly
+ quoted in pg_dump output. This would
+ cause problems if settings for these variables appeared in
+ CREATE FUNCTION ... SET or ALTER
+ DATABASE/ROLE ... SET clauses.
+
+
+
+
+
+ Fix overflow handling in PL/pgSQL
+ integer FOR loops (Tom Lane)
+
+
+
+ The previous coding failed to detect overflow of the loop variable
+ on some non-gcc compilers, leading to an infinite loop.
+
+
+
+
+
+ Adjust PL/Python regression tests to pass
+ under Python 3.7 (Peter Eisentraut)
+
+
+
+
+
+ Support testing PL/Python and related
+ modules when building with Python 3 and MSVC (Andrew Dunstan)
+
+
+
+
+
+ Rename internal b64_encode
+ and b64_decode functions to avoid conflict with
+ Solaris 11.4 built-in functions (Rainer Orth)
+
+
+
+
+
+ Sync our copy of the timezone library with IANA tzcode release 2018e
+ (Tom Lane)
+
+
+
+ This fixes the zic timezone data compiler
+ to cope with negative daylight-savings offsets. While
+ the PostgreSQL project will not
+ immediately ship such timezone data, zic
+ might be used with timezone data obtained directly from IANA, so it
+ seems prudent to update zic now.
+
+
+
+
+
+ Update time zone data files to tzdata
+ release 2018d for DST law changes in Palestine and Antarctica (Casey
+ Station), plus historical corrections for Portugal and its colonies,
+ as well as Enderbury, Jamaica, Turks & Caicos Islands, and
+ Uruguay.

+ server error is reported after a large amount of query output has
+ been collected (Tom Lane)
+
+
+
+ Discard the previous output before, not after, processing the error
+ message. On some platforms, notably Linux, this can make a
+ difference in the application's subsequent memory footprint.
+
+
+
+
+
+ Fix double-free crashes in ecpg
+ (Patrick Krecker, Jeevan Ladhe)
+
+
+
+
+
+ Fix ecpg to handle long long
+ int variables correctly in MSVC builds (Michael Meskes,
+ Andrew Gierth)
+
+
+
+
+
+ Fix mis-quoting of values for list-valued GUC variables in dumps
+ (Michael Paquier, Tom Lane)
+
+
+
+ The local_preload_libraries,
+ session_preload_libraries,
+ shared_preload_libraries,
+ and temp_tablespaces variables were not correctly
+ quoted in pg_dump output. This would
+ cause problems if settings for these variables appeared in
+ CREATE FUNCTION ... SET or ALTER
+ DATABASE/ROLE ... SET clauses.
+
+
+
+
+
+ Fix pg_recvlogical to not fail against
+ pre-v10 PostgreSQL servers
+ (Michael Paquier)
+
+
+
+ A previous fix caused pg_recvlogical to
+ issue a command regardless of server version, but it should only be
+ issued to v10 and later servers.
+
+
+
+
+
+ Ensure that pg_rewind deletes files on the
+ target server if they are deleted from the source server during the
+ run (Takayuki Tsunakawa)
+
+
+
+ Failure to do this could result in data inconsistency on the target,
+ particularly if the file in question is a WAL segment.
+
+
+
+
+
+ Fix pg_rewind to handle tables in
+ non-default tablespaces correctly (Takayuki Tsunakawa)
+
+
+
+
+
+ Fix overflow handling in PL/pgSQL
+ integer FOR loops (Tom Lane)
+
+
+
+ The previous coding failed to detect overflow of the loop variable
+ on some non-gcc compilers, leading to an infinite loop.
+
+
+
+
+
+ Adjust PL/Python regression tests to pass
+ under Python 3.7 (Peter Eisentraut)
+
+
+
+
+
+ Support testing PL/Python and related
+ modules when building with Python 3 and MSVC (Andrew Dunstan)
+
+
+
+
+
+
+ Support building with Microsoft Visual Studio 2015 (Michael Paquier)
+
+
+
+ Various fixes needed for VS2015 compatibility were previously
+ back-patched into the 9.5 branch, but this one was missed.
+
+
+
+
+
+ Rename internal b64_encode
+ and b64_decode functions to avoid conflict with
+ Solaris 11.4 built-in functions (Rainer Orth)
+
+
+
+
+
+ Sync our copy of the timezone library with IANA tzcode release 2018e
+ (Tom Lane)
+
+
+
+ This fixes the zic timezone data compiler
+ to cope with negative daylight-savings offsets. While
+ the PostgreSQL project will not
+ immediately ship such timezone data, zic
+ might be used with timezone data obtained directly from IANA, so it
+ seems prudent to update zic now.
+
+
+
+
+
+ Update time zone data files to tzdata
+ release 2018d for DST law changes in Palestine and Antarctica (Casey
+ Station), plus historical corrections for Portugal and its colonies,
+ as well as Enderbury, Jamaica, Turks & Caicos Islands, and
+ Uruguay.
