Fix introduced in [1]: plperl.on_init = 'use utf8; use re; package utf8; require "utf8_heavy.pl";' now causes plperl functions to fail with: ERROR: attempt to redefine parameter "plperl.use_strict" which is an unhelpful error message indicating a missing module [2]. utf8_heavy.pl has been dropped by Perl [3]. Original example code from [1] now runs fine for me without defining plperl.on_init.

When migrating from 15 to 16 this default config setting causes the process to fail if any database makes use of plperl or plperlu with the following error: could not load library "$libdir/plperl": ERROR: CONTEXT: while running Perl initialization updating the config to the below prevents the issue. plperl.on_init = 'use utf8; use re; package utf8;' However I do not know what the impact of this change is and if Unicode::UCD should replace utf8_heavy.pl.
