35f4994133 Fix plperl and pltcl error handling per my previous proposal. SPI
operations are now run as subtransactions, so that errors in them
can be reported as ordinary Perl or Tcl errors and caught by the
normal error handling convention of those languages.  Also do some
minor code cleanup in pltcl.c: extract a large chunk of duplicated
code in pltcl_SPI_execute and pltcl_SPI_execute_plan into a shared
subroutine.

ea23ec82c2 Remove GUC USERLIMIT variable category, making the affected variables
plain SUSET instead.  Also delay processing of options received in
client connection request until after we know if the user is a superuser,
so that SUSET values can be set that way by legitimate superusers.
