I’ve been experiencing problems getting any plperl function working, and I believe the problem lies in the actual plperl installation not due to my rusty perl memories. For example, the very simple plperl example in the comprehensive documentation (at http://www.postgresql.org/docs/8.4/interactive/plperl-funcs.html):
CREATE FUNCTION perl_max (integer, integer) RETURNS integer AS $$
if ($_[0] > $_[1]) { return $_[0]; }
return $_[1];
$$ LANGUAGE plperl;
Returns something odd (at least to me, also with little postgresql experience):
prod1=> select perl_max(1,2);
ERROR: invalid input syntax for integer: "CODE(0x1f6d13c)"
I have seen something similar to "CODE(0x...)" show up in other programs, but because the input parameter on those was TEXT I didn’t get an error... the program just behaved very confusingly until I realized that the correct text input was being replaced with “CODE(0x...)". At least in this example, I get an actual error because the input variable doesn’t match type.
Thanks for any help you can tell me on how to fix this!
