postgresql-8.1 8.1.23-0ubuntu0.6.06 source package in Ubuntu

Changelog

postgresql-8.1 (8.1.23-0ubuntu0.6.06) dapper-proposed; urgency=low

  * New upstream bug fix release (LP: #693157):
    - Force the default wal_sync_method to be fdatasync on Linux.
      The default on Linux has actually been fdatasync for many years,
      but recent kernel changes caused PostgreSQL to choose open_datasync
      instead. This choice did not result in any performance improvement,
      and caused outright failures on certain filesystems, notably ext4
      with the data=journal mount option.
    - Fix recovery from base backup when the starting checkpoint WAL
      record is not in the same WAL segment as its redo point.
    - Add support for detecting register-stack overrun on IA64.
      The IA64 architecture has two hardware stacks. Full prevention of
      stack-overrun failures requires checking both.
    - Add a check for stack overflow in copyObject().
      Certain code paths could crash due to stack overflow given a
      sufficiently complex query.
    - Fix detection of page splits in temporary GiST indexes.
      It is possible to have a "concurrent" page split in a temporary
      index, if for example there is an open cursor scanning the index
      when an insertion is done. GiST failed to detect this case and
      hence could deliver wrong results when execution of the cursor
      continued.
    - Avoid memory leakage while "ANALYZE"'ing complex index expressions.
    - Ensure an index that uses a whole-row Var still depends on its
      table.
      An index declared like create index i on t (foo(t.-)) would not
      automatically get dropped when its table was dropped.
    - Do not "inline" a SQL function with multiple OUT parameters.
      This avoids a possible crash due to loss of information about the
      expected result rowtype.
    - Fix constant-folding of COALESCE() expressions.
      The planner would sometimes attempt to evaluate sub-expressions
      that in fact could never be reached, possibly leading to unexpected
      errors.
    - Add print functionality for InhRelation nodes.
      This avoids a failure when debug_print_parse is enabled and certain
      types of query are executed.
    - Fix incorrect calculation of distance from a point to a horizontal
      line segment.
      This bug affected several different geometric distance-measurement
      operators.
    - Fix PL/pgSQL's handling of "simple" expressions to not fail in
      recursion or error-recovery cases.
    - Fix bug in "contrib/cube"'s GiST picksplit algorithm.
      This could result in considerable inefficiency, though not actually
      incorrect answers, in a GiST index on a cube column. If you have
      such an index, consider "REINDEX"ing it after installing this
      update.
    - Don't emit "identifier will be truncated" notices in
      "contrib/dblink" except when creating new connections.
    - Fix potential coredump on missing public key in "contrib/pgcrypto".
    - Fix memory leak in "contrib/xml2"'s XPath query functions.
