Обсуждение: pgsql: Fix handling of "undef" in contrib/jsonb_plperl.
Fix handling of "undef" in contrib/jsonb_plperl. Perl has multiple internal representations of "undef", and just testing for SvTYPE(x) == SVt_NULL doesn't recognize all of them, leading to "cannot transform this Perl type to jsonb" errors. Use the approved test SvOK() instead. Report and patch by Ivan Panchenko. Back-patch to v11 where this module was added.
