Hi all,
I was wondering if postgres can return the last ID inserted for a table
which the primary key is autoincremented. I need to retrieve this ID in my
code to continue processing on that inserted row.
Thanks to all

smarlowe=# create table test (a serial primary key, b text);
NOTICE: CREATE TABLE will create implicit sequence "test_a_seq" for
serial column "test.a"
NOTICE: CREATE TABLE / PRIMARY KEY will create implicit index
"test_pkey" for table "test"
CREATE TABLE
smarlowe=# insert into test (a,b) values (DEFAULT,'test') returning a;
a
---
1
(1 row)
INSERT 0 1
Note that there are other ways of doing it, but I really like the
returning clause.

Nice idea but how can I use this in a frontend that I am developing using
Delphi and ADO objects ?

Either with RETURNING:
http://www.postgresql.org/docs/current/static/sql-insert.html
or with currval():

Use select currval() on the sequence name.
