Also, on my systems the trigger isn't necessary, but the function
call history is significant. This is in HEAD:
\c test
CREATE OR REPLACE FUNCTION foo() RETURNS text AS $$
return "foo";
$$ LANGUAGE plperl;
CREATE OR REPLACE FUNCTION bar() RETURNS text AS $$
my $rv = spi_exec_query("SELECT foo() AS x");
return $rv->{rows}[0]->{x};
$$ LANGUAGE plperl;
\c test
SELECT bar();
ERROR: error from Perl function: creation of Perl function failed: (in cleanup) Undefined subroutine
&main::mksafefunccalled at (eval 5) line 2. at (eval 5) line 2.
SELECT bar();
ERROR: error from Perl function: creation of Perl function failed: (in cleanup) Undefined subroutine
&main::mksafefunccalled at (eval 5) line 2. at (eval 5) line 2.
SELECT foo();
foo
-----
foo
(1 row)
SELECT bar();
bar
-----
foo
(1 row)
I verified that the postmaster is using a current plperl.so by
adding a debugging ereport() statement in plperl_call_perl_func()
(output not shown above).
