OK, we've made good progress with the PL/Perl patches, and this one is
next on the queue.

It should also be noted that as proposed END blocks will not run at all
in the postmaster, even if perl is preloaded in the postmaster and the
preloaded code sets END handlers. That makes setting them rather safer,
ISTM.

So, are there still objections to applying this patch?

(Note, this is different from the proposal to specify on_trusted_init
and on_untrusted_init handlers. The on_perl_init handler would be run on
library load, and is mainly for the purpose of preloading perl modules
and the like).

cheers
