E.42. Release 8.1.6

Release date: 2007-01-08

This release contains a variety of fixes from 8.1.5. For information about new features in the 8.1 major release, see Section E.48.

E.42.1. Migration to Version 8.1.6

A dump/restore is not required for those running 8.1.X. However, if you are upgrading from a version earlier than 8.1.2, see the release notes for 8.1.2.

E.42.2. Changes

  • Improve handling of getaddrinfo() on AIX (Tom)

    This fixes a problem with starting the statistics collector, among other things.

  • Fix pg_restore to handle a tar-format backup that contains large objects (blobs) with comments (Tom)

  • Fix "failed to re-find parent key" errors in VACUUM (Tom)

  • Clean out pg_internal.init cache files during server restart (Simon)

    This avoids a hazard that the cache files might contain stale data after PITR recovery.

  • Fix race condition for truncation of a large relation across a gigabyte boundary by VACUUM (Tom)

  • Fix bug causing needless deadlock errors on row-level locks (Tom)

  • Fix bugs affecting multi-gigabyte hash indexes (Tom)

  • Fix possible deadlock in Windows signal handling (Teodor)

  • Fix error when constructing an ARRAY[] made up of multiple empty elements (Tom)

  • Fix ecpg memory leak during connection (Michael)

  • Fix for Darwin (OS X) compilation (Tom)

  • to_number() and to_char(numeric) are now STABLE, not IMMUTABLE, for new initdb installs (Tom)

    This is because lc_numeric can potentially change the output of these functions.

  • Improve index usage of regular expressions that use parentheses (Tom)

    This improves psql \d performance also.

  • Update timezone database

    This affects Australian and Canadian daylight-savings rules in particular.
