Seems like there should be a bar return at the end of the function, otherwise
it returns the last expression, which happens to be a code reference. Not very
useful in a function that should return VOID. New version:
CREATE OR REPLACE FUNCTION myfuncs() RETURNS void AS $$
$_SHARED{myquote} = sub {
my $arg = shift;
$arg =~ s/(['\\])/\\$1/g;
return "'$arg'";
};
return;
$$ LANGUAGE plperl;
