Release date: 2012-09-24
This release contains a variety of fixes from 8.3.20. For information about new features in the 8.3 major release, see Section E.178.
The PostgreSQL community will stop releasing updates for the 8.3.X release series in February 2013. Users are encouraged to update to a newer release branch soon.
A dump/restore is not required for those running 8.3.X.
However, if you are upgrading from a version earlier than 8.3.17, see Section E.161.
Improve page-splitting decisions in GiST indexes (Alexander Korotkov, Robert Haas, Tom Lane)
Multi-column GiST indexes might suffer unexpected bloat due to this error.
Fix cascading privilege revoke to stop if privileges are still held (Tom Lane)
If we revoke a grant option from some role X, but
X still holds that option via a grant from someone
else, we should not recursively revoke the corresponding privilege
from role(s) Y that X had granted it
to.
Fix handling of SIGFPE when PL/Perl is in use (Andres Freund)
Perl resets the process's SIGFPE handler to
SIG_IGN, which could result in crashes later on. Restore
the normal Postgres signal handler after initializing PL/Perl.
Prevent PL/Perl from crashing if a recursive PL/Perl function is redefined while being executed (Tom Lane)
Work around possible misoptimization in PL/Perl (Tom Lane)
Some Linux distributions contain an incorrect version of
pthread.h that results in incorrect compiled code in
PL/Perl, leading to crashes if a PL/Perl function calls another one
that throws an error.
Update time zone data files to tzdata release 2012f for DST law changes in Fiji
