Not to say that perl and complex are redundant, but does the id go away after the NOT FOUND exception?

The function does a select to see if the id number exists, and it fails.  NOT FOUND causes a RAISE EXCEPTION.

It is a fairly large and complex Perl program, so no, not really.

I do an insert via a function, which returns the new id, then later I try to SELECT on that id, and it doesn't find it.

Could it be because the insert is done inside a function?

Can you share the code that does not work with us?  Preferably as a small self-contained example.
