Description:        table with a serial field don't works
Details:

I've installed postgres on 2 pcs, a win2000 and a winxp home.
when i create a table with a SERIAL field, the pgadmin can see and use it,
but with psql or a .net program using odbc, ole or lpgsql, the error is
"RELATION *tablename* NOT FOUND".
i tryed to use psql and the .net program on the same pc, or a lan-connected
pc.
If i change the type of the field originally SERIAL, the error vanish.

i searched on forums, but none knows that problems.
