PostgreSQL versions in pkgsrc.

* Add new configuration parameter ssl_renegotiation_limit to control
how often we do session key renegotiation for an SSL connection
* Fix possible deadlock during backend startup
* Fix possible crashes due to not handling errors during relcache
reload cleanly
* Fix possible crashes when trying to recover from a failure in
subtransaction start
* Fix server memory leak associated with use of savepoints and a
client encoding different from server's encoding
* Fix incorrect WAL data emitted during end-of-recovery cleanup of a
GIST index page split
* Make substring() for 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
* Fix some cases of pathologically slow regular expression matching
* 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
* Fix some more cases of temporary-file leakage
* Improve constraint exclusion processing of boolean-variable cases,
in particular make it possible to exclude a partition that has a
"bool_column = false" constraint
* 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
* Prevent infinite loop on some platforms if a directory is named as
an inclusion target in "pg_hba.conf" and related files
* Fix possible infinite loop if SSL_read or SSL_write fails without
setting errno
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
* 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"
* Fix plpgsql failure in one case where a composite column is set to NULL
* Fix possible failure when calling PL/Perl functions from PL/PerlU
or vice versa
* Add volatile markings in PL/Python to avoid possible
compiler-specific misbehavior
* Ensure PL/Tcl initializes the Tcl interpreter fully
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
* Fix assorted crashes in "contrib/xml2" caused by sloppy memory
management
* Make building of "contrib/xml2" more robust on Windows
* Fix race condition in Windows signal handling
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.

* Prevent error recursion crashes when encoding conversion fails.
* Disallow "CREATE CONVERSION" with the wrong encodings for the
specified conversion function.
* Fix core dump when to_char() is given format codes that are
inappropriate for the type of the data argument.
* Fix possible failure in "contrib/tsearch2" when C locale is used
with a multi-byte encoding.
* Fix extreme inefficiency in "contrib/tsearch2" parser's handling of
an email-like string containing multiple @ characters.
* Fix decompilation of CASE WHEN with an implicit coercion.
* Fix possible misassignment of the owner of a TOAST table's rowtype.
* Fix PL/pgSQL to not treat INTO after "INSERT" as an INTO-variables
clause anywhere in the string, not only at the start; in
particular, don't fail for "INSERT INTO" within "CREATE RULE".
* Clean up PL/pgSQL error status variables fully at block exit.
* Retry failed calls to CallNamedPipe() on Windows.
* Add MUST (Mauritius Island Summer Time) to the default list of
known timezone abbreviations.

* Fix character string comparison for Windows locales that consider
different character combinations as equal
* Repair potential deadlock between concurrent "VACUUM FULL"
operations on different system catalogs
* Fix longstanding "LISTEN"/"NOTIFY" race condition
* Disallow "LISTEN" and "UNLISTEN" within a prepared transaction
* Disallow dropping a temporary table within a prepared transaction
* Fix rare crash when an error occurs during a query using a hash
index
* Fix memory leaks in certain usages of set-returning functions
* Fix input of datetime values for February 29 in years BC

OWNER"
* Ensure pg_stat_activity.waiting flag is cleared when a lock wait is
aborted
* Fix handling of process permissions on Windows Vista
