It doesn't work in 8.1 either:
Welcome to psql 8.1.16, the PostgreSQL interactive terminal.
Type: \copyright for distribution terms
\h for help with SQL commands
\? for help with psql commands
\g or terminate with semicolon to execute query
\q to quit
regression=# create table test (a serial, b int);
NOTICE: CREATE TABLE will create implicit sequence "test_a_seq" for serial column "test.a"
CREATE TABLE
regression=# insert into test (b) select currval('test_a_seq'::regclass);
ERROR: currval of sequence "test_a_seq" is not yet defined in this session
regression=#
There must be something else that you changed about your application.
