Add new configuration parameter ssl_renegotiation_limit to
control how often we do session key renegotiation for an SSL connection
(Magnus)
This can be set to zero to disable renegotiation completely, which may
be required if a broken SSL library is used. In particular, some
vendors are shipping stopgap patches for CVE-2009-3555 that cause
renegotiation attempts to fail.
Fix possible deadlock during backend startup (Tom)
Fix possible crashes due to not handling errors during relcache reload
cleanly (Tom)
Fix possible crashes when trying to recover from a failure in
subtransaction start (Tom)
Fix server memory leak associated with use of savepoints and a client
encoding different from server's encoding (Tom)
Fix incorrect WAL data emitted during end-of-recovery cleanup of a GIST
index page split (Yoichi Hirai)
This would result in index corruption, or even more likely an error
during WAL replay, if we were unlucky enough to crash during
end-of-recovery cleanup after having completed an incomplete GIST
insertion.
Make substring() for bit types treat any negative
length as meaning "all the rest of the string" (Tom)
The previous coding treated only -1 that way, and would produce an
invalid result value for other negative values, possibly leading to
a crash (CVE-2010-0442).
Fix integer-to-bit-string conversions to handle the first fractional
byte correctly when the output bit width is wider than the given
integer by something other than a multiple of 8 bits (Tom)
Fix some cases of pathologically slow regular expression matching (Tom)
Fix the STOP WAL LOCATION entry in backup history files to
report the next WAL segment's name when the end location is exactly at a
segment boundary (Itagaki Takahiro)
Fix some more cases of temporary-file leakage (Heikki)
This corrects a problem introduced in the previous minor release.
One case that failed is when a plpgsql function returning set is
called within another function's exception handler.
Improve constraint exclusion processing of boolean-variable cases,
in particular make it possible to exclude a partition that has a
"bool_column = false" constraint (Tom)
When reading pg_hba.conf and related files, do not treat
@something as a file inclusion request if the @
appears inside quote marks; also, never treat @ by itself
as a file inclusion request (Tom)
This prevents erratic behavior if a role or database name starts with
@. If you need to include a file whose path name
contains spaces, you can still do so, but you must write
@"/path to/file" rather than putting the quotes around
the whole construct.
Prevent infinite loop on some platforms if a directory is named as
an inclusion target in pg_hba.conf and related files
(Tom)
Fix possible infinite loop if SSL_read or
SSL_write fails without setting errno (Tom)
This is reportedly possible with some Windows versions of
openssl.
Fix psql's numericlocale option to not
format strings it shouldn't in latex and troff output formats (Heikki)
Make psql return the correct exit status (3) when
ON_ERROR_STOP and --single-transaction are
both specified and an error occurs during the implied COMMIT
(Bruce)
Fix plpgsql failure in one case where a composite column is set to NULL
(Tom)
Fix possible failure when calling PL/Perl functions from PL/PerlU
or vice versa (Tim Bunce)
Add volatile markings in PL/Python to avoid possible
compiler-specific misbehavior (Zdenek Kotala)
Ensure PL/Tcl initializes the Tcl interpreter fully (Tom)
The only known symptom of this oversight is that the Tcl
clock command misbehaves if using Tcl 8.5 or later.
Prevent crash in contrib/dblink when too many key
columns are specified to a dblink_build_sql_* function
(Rushabh Lathia, Joe Conway)
Fix assorted crashes in contrib/xml2 caused by sloppy
memory management (Tom)
Make building of contrib/xml2 more robust on Windows
(Andrew)
Fix race condition in Windows signal handling (Radu Ilie)
One known symptom of this bug is that rows in pg_listener
could be dropped under heavy load.
Update time zone data files to tzdata release 2010e
for DST law changes in Bangladesh, Chile, Fiji, Mexico, Paraguay, Samoa.
