Release date: 2010-03-15
This release contains a variety of fixes from 8.1.19. For information about new features in the 8.1 major release, see Section E.253.
A dump/restore is not required for those running 8.1.X. However, if you are upgrading from a version earlier than 8.1.18, see Section E.235.
Add new configuration parameter
ssl_renegotiation_limit to control how
often we do session key renegotiation for an SSL
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 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)
bit types treat any negative
length as meaning “all the rest of the string”
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)
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.
and related files, do not treat
@something as a file inclusion request
@ appears inside
quote marks; also, never treat
@ by itself as a file inclusion request
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)
numericlocale option to not
format strings it shouldn't in latex and troff output
Fix plpgsql failure in one case where a composite column is set to NULL (Tom)
volatile markings in
PL/Python to avoid possible compiler-specific misbehavior
Ensure PL/Tcl initializes the Tcl interpreter fully (Tom)
The only known symptom of this oversight is that the
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
Update time zone data files to tzdata release 2010e for DST law changes in Bangladesh, Chile, Fiji, Mexico, Paraguay, Samoa.
