Hi all, is there any way to exploit sub signatures in PL/Perl? The following is not working, I suspect it is not possible due to the way PL/Perl compiles the code. testdb=# create or replace function f( a int ) returns text as $$ use feature 'signatures'; elog( INFO, "Perl version $^V" ); elog(INFO, "A = $a" ); return "A=$a"; $$ language plperlu; testdb=# select f( 10 ); INFO: Perl version v5.32.1 INFO: A = f ---- A= (1 row)
