E.167.2. Changes

  • 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
