* 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. |
