You certainly can use currval();
In session #1 I do...
jseymour=> create table foo3 (bar serial, baz int);
jseymour=> insert into foo3 (baz) values (1);
This will put "1" in for column "bar".
In session #2 I do...
jseymour=> insert into foo3 (baz) values (1);
This will put "2" in for column "bar".
Now back to session #1...
jseymour=> select currval('foo3_bar_seq');
currval
---------
1
(1 row)
And session #2...
jseymour=> select currval('foo3_bar_seq');
currval
---------
2
(1 row)
HTH,
