hi Alvaro Herrera
You use the currval() function, using the name of the involved sequence
as parameter. There is a pg_get_serial_sequence() function, to which
you give the table name and column name
thx for the information
and is there a function i can use to get the last added autonumber without
knowing wich table or row? (exactly as select @@ IDENTITY does?) i have read in
the messages that there must be such a function for version 8.0, but i could
not find it in the documentation, any idea on it?

(windowsinstaller) on a xp prof platform
i would like to get back the autonumber from the last record inserted,
for other SQL db (m$ sql db ...) i could use:
SELECT @@ IDENTITY
can someone help me by informing me what the SQL syntax is to be used
with PostGreSQL db and get the same result, the last autonumber inserted?

you give the table name and column name, and it will give you the
sequence name.
