Hmmm...even if the "plperl" custom variable class isn't defined in
postgresql.conf, plperl.use_strict springs into existence when the
interpreter is initialized:

test=> SET plperl.use_strict TO on;
ERROR:  unrecognized configuration parameter "plperl.use_strict"
test=> CREATE FUNCTION foo() RETURNS void AS $$$$ LANGUAGE plperl;
CREATE FUNCTION
test=> SET plperl.use_strict TO on;
SET
test=> CREATE OR REPLACE FUNCTION foo() RETURNS void AS $$ $x = 1234; $$ LANGUAGE plperl;
ERROR:  creation of Perl function failed: Global symbol "$x" requires explicit package name at (eval 8) line 1.
test=> SET plperl.use_strict TO off;
SET
test=> CREATE OR REPLACE FUNCTION foo() RETURNS void AS $$ $x = 1234; $$ LANGUAGE plperl;
CREATE FUNCTION

Is such automatic creation of a GUC variable intended?  If so,
couldn't you exploit that in regression tests?
