* New upstream bug fix release:
- Fix catalog cache invalidation after a "VACUUM FULL" or "CLUSTER"
on a system catalog. In some cases the relocation of a system catalog
row to another place would not be recognized by concurrent server
processes, allowing catalog corruption to occur if they then tried to
update that row. The worst-case outcome could be as bad as complete loss
of a table.
- Fix incorrect order of operations during sinval reset processing,
and ensure that TOAST OIDs are preserved in system catalogs.
These mistakes could lead to transient failures after a "VACUUM
FULL" or "CLUSTER" on a system catalog.
- Fix bugs in indexing of in-doubt HOT-updated tuples.
These bugs could result in index corruption after reindexing a
system catalog. They are not believed to affect user indexes.
- Fix multiple bugs in GiST index page split processing.
- Fix possible buffer overrun in tsvector_concat().
- Fix crash in xml_recv when processing a "standalone" parameter.
- Make pg_options_to_table return NULL for an option with no value.
Previously such cases would result in a server crash.
- Avoid possibly accessing off the end of memory in "ANALYZE" and in
SJIS-2004 encoding conversion.
This fixes some very-low-probability server crash scenarios.
- Protect pg_stat_reset_shared() against NULL input.
- Fix possible failure when a recovery conflict deadlock is detected
within a sub-transaction.
- Avoid spurious conflicts while recycling btree index pages during
hot standby.
- Shut down WAL receiver if it's still running at end of recovery.
The postmaster formerly panicked in this situation, but it's
actually a legitimate case.
- Fix race condition in relcache init file invalidation.
There was a window wherein a new backend process could read a stale
init file but miss the inval messages that would tell it the data
is stale. The result would be bizarre failures in catalog accesses,
typically "could not read block 0 in file ..." later during
startup.
- Fix memory leak at end of a GiST index scan.
- Fix memory leak when encoding conversion has to be done on incoming
command strings and "LISTEN" is active.
- Fix incorrect memory accounting (leading to possible memory bloat)
in tuplestores supporting holdable cursors and plpgsql's RETURN
NEXT command.
- Fix trigger WHEN conditions when both BEFORE and AFTER triggers
exist. Evaluation of WHEN conditions for AFTER ROW UPDATE triggers
could crash if there had been a BEFORE ROW trigger fired for the same
update.
- Fix performance problem when constructing a large, lossy bitmap.
- Fix join selectivity estimation for unique columns.
- Fix nested PlaceHolderVar expressions that appear only in
sub-select target lists. This mistake could result in outputs of an
outer join incorrectly appearing as NULL.
- Allow the planner to assume that empty parent tables really are
empty. Normally an empty table is assumed to have a certain minimum
size for planning purposes; but this heuristic seems to do more harm
than good for the parent table of an inheritance hierarchy, which
often is permanently empty.
- Allow nested EXISTS queries to be optimized properly.
- Fix array- and path-creating functions to ensure padding bytes are
zeroes. This avoids some situations where the planner will think that
semantically-equal constants are not equal, resulting in poor
optimization.
- Fix "EXPLAIN" to handle gating Result nodes within inner-indexscan
subplans. The usual symptom of this oversight was "bogus varno" errors.
- Fix btree preprocessing of "indexedcol" IS NULL conditions.
Such a condition is unsatisfiable if combined with any other type
of btree-indexable condition on the same index column. The case was
handled incorrectly in 9.0.0 and later, leading to query output
where there should be none.
- Work around gcc 4.6.0 bug that breaks WAL replay.
This could lead to loss of committed transactions after a server
crash.
- Fix dump bug for VALUES in a view.
- Disallow SELECT FOR UPDATE/SHARE on sequences.
This operation doesn't work as expected and can lead to failures.
- Fix "VACUUM" so that it always updates pg_class.reltuples/relpages.
This fixes some scenarios where autovacuum could make increasingly
poor decisions about when to vacuum tables.
- Defend against integer overflow when computing size of a hash table.
- Fix cases where "CLUSTER" might attempt to access already-removed
TOAST data.
- Fix premature timeout failures during initial authentication
transaction.
- Fix portability bugs in use of credentials control messages for
"peer" authentication. (see #627596, already fixed in Debian before)
- Fix SSPI login when multiple roundtrips are required. The typical
symptom of this problem was "The function requested is not supported"
errors during SSPI login.
- Fix failure when adding a new variable of a custom variable class
to "postgresql.conf".
- Throw an error if "pg_hba.conf" contains hostssl but SSL is
disabled. This was concluded to be more user-friendly than the previous
behavior of silently ignoring such lines.
- Fix failure when "DROP OWNED BY" attempts to remove default
privileges on sequences.
- Fix typo in pg_srand48 seed initialization.
This led to failure to use all bits of the provided seed. This
function is not used on most platforms (only those without
srandom), and the potential security exposure from a
less-random-than-expected seed seems minimal in any case.
- Avoid integer overflow when the sum of LIMIT and OFFSET values
exceeds 2^63.
- Add overflow checks to int4 and int8 versions of generate_series()
- Fix trailing-zero removal in to_char(). In a format with FM and no digit
positions after the decimal point, zeroes to the left of the decimal
point could be removed incorrectly.
- Fix pg_size_pretty() to avoid overflow for inputs close to 2^63.
- Weaken plpgsql's check for typmod matching in record values.
An overly enthusiastic check could lead to discarding length
modifiers that should have been kept.
- In pg_upgrade, avoid dumping orphaned temporary tables. This prevents
situations wherein table OID assignments could get out of sync between old
and new installations.
- Fix pg_upgrade to preserve toast tables' relfrozenxids during an
upgrade from 8.3. Failure to do this could lead to "pg_clog" files being
removed too soon after the upgrade.
- Fix psql's counting of script file line numbers during COPY from a
different file.
- Fix pg_restore's direct-to-database mode for
standard_conforming_strings. pg_restore could emit incorrect commands
when restoring directly to a database server from an archive file that
had been made with standard_conforming_strings set to on.
- Be more user-friendly about unsupported cases for parallel
pg_restore. This change ensures that such cases are detected and
reported before any restore actions have been taken.
- Fix write-past-buffer-end and memory leak in libpq's LDAP service
lookup code.
- In libpq, avoid failures when using nonblocking I/O and an SSL
connection.
- Improve libpq's handling of failures during connection startup.
In particular, the response to a server report of fork() failure
during SSL connection startup is now saner.
- Improve libpq's error reporting for SSL failures.
- Fix PQsetvalue() to avoid possible crash when adding a new tuple to
a PGresult originally obtained from a server query.
- Make ecpglib write double values with 15 digits precision.
- In ecpglib, be sure LC_NUMERIC setting is restored after an error.
- Apply upstream fix for blowfish signed-character bug
(CVE-2011-2483) (Tom Lane) (Closes: #636571)
"contrib/pg_crypto"'s blowfish encryption code could give wrong
results on platforms where char is signed (which is most), leading
to encrypted passwords being weaker than they should be.
- Fix memory leak in "contrib/seg".
- Fix pgstatindex() to give consistent results for empty indexes.
- Allow building with perl 5.14. (Closes: #628505)
* Drop 03-cmsgcred-size.patch. Fixed upstream in a different way.
