Log Message:
-----------
While fixing plperl and pltcl, I realized plpgsql wasn't doing
subtransactions quite right either: the ReleaseCurrentSubTransaction
call should occur inside the PG_TRY, so that the proper path is taken
if an error occurs during subtransaction commit. This assumes that
AbortSubTransaction can cope with the state left behind if
CommitSubTransaction fails partway through, but we were already
requiring that.

TIP 9: the planner will ignore your desire to choose an index scan if your
joining column's datatypes do not match
