Under high load, Windows processes will sometimes fail at startup with

this error code. Formerly the postmaster treated this as a panic

condition and restarted the whole database, but that seems to be

an overreaction.

code can be used with older server versions. Note that the patch will

be effective only after <filename>contrib/hstore</> is installed or

reinstalled in a particular database. Users might prefer to execute

Under high load, Windows processes will sometimes fail at startup with

this error code. Formerly the postmaster treated this as a panic

condition and restarted the whole database, but that seems to be
|

an overreaction.

This is a back-patch of an 8.4 fix that was missed in the 8.3 branch.

This corrects an error introduced in 8.3.8 that could cause incorrect
|
||||||
|
results for outer joins when the inner relation is an inheritance tree
|
||||||
|
or <literal>UNION ALL</> subquery.
