Yes...

OK I prepared what you asked and I tested it myself before sending.

And I think I've found the problem (but not the solution !) :

When I dump the FUNCTION, I get this :

> CREATE test(character varying) RETURNS SETOF serial_number

instead of this :

> CREATE test(character varying) RETURNS SETOF rma.serial_number

That seems to be some bug in Postgres ?

The problem is then clear, it doesn't take SETOF rma.serial_number but
SETOF public.serial_number

Do you see how we could solve this ? And do you think this is the problem ?

Thanks a lot again for all your help !
