* Improve handling of URLs in headline() function * Improve handling of overlength headlines in headline() function * Prevent possible Assert failure or misconversion if an encoding conversion is created with the wrong conversion function for the specified pair of encodings * Fix possible Assert failure if a statement executed in PL/pgSQL is rewritten into another kind of statement, for example if an "INSERT" is rewritten into an "UPDATE" * Ensure that a snapshot is available to datatype input functions * Make it safer for SPI-using functions to be used within datatype I/O; in particular, to be used in domain check constraints * Avoid unnecessary locking of small tables in "VACUUM" * Fix a problem that made UPDATE RETURNING tableoid return zero instead of the correct OID * Fix planner misestimation of selectivity when transitive equality is applied to an outer-join clause This could result in bad plans for queries like ... from a left join b on a.a1 = b.b1 where a.a1 = 42 ... * Improve optimizer's handling of long IN lists This change avoids wasting large amounts of time on such lists when constraint exclusion is enabled. * Ensure that the contents of a holdable cursor don't depend on the contents of TOAST tables * Fix memory leak when a set-returning function is terminated without reading its whole result * Fix "contrib/dblink"'s dblink_get_result(text,bool) function * Fix possible garbage output from "contrib/sslinfo" functions * Fix configure script to properly report failure when unable to obtain linkage information for PL/Perl * Make all documentation reference pgsql-bugs and/or pgsql-hackers as appropriate, instead of the now-decommissioned pgsql-ports and pgsql-patches mailing lists * Update time zone data files to tzdata release 2009a (for Kathmandu and historical DST corrections in Switzerland, Cuba) |
