Hi Gaetano,
Postgresql implements serial field using sequences.
detailed description of sequences are avaliable at
http://www.postgresql.org/idocs/index.php?functions-sequence.html
a NICE flash tutorial is also available at:
http://techdocs.postgresql.org/college/001_sequences/
the specific answer to your question is the function "currval(sequence_name)"
can be used.
you can get the name of sequenced being used for the serial field by
describing the table (\d tablename).
But the very idea of inserting the value and then retriving the sequence
number sounds fishy to me. Why not get the sequence number first and than
insert using that seqnce number (more on the flash tutorial ).
