Given the discussion in this thread, I intend to mark the commitfest entry as Withdrawn shortly. Before I do, I thought I'd first check whether 0001 [0] might be worthwhile independent of $SUBJECT. This change separates the [un]trusted handler and validator functions for PL/Perl so that we no longer need to inspect pg_language to determine whether to use the trusted or untrusted code path. I was surprised to learn that you can end up with PL/PerlU even if you've specified the trusted handler/validator functions. Besides bringing things more in line with how PL/Tcl does things, this change simplifies function lookup in plperl_proc_hash. I suppose such a change might introduce a compatibility break for users who are depending on this behavior, but I don't know if that's worth worrying about.
