I'm rather new to Postgres and Navicat is the only fully functional GUI that I've come across. That said, I'm trying to implement a simple auto increment for an id. Navicat doesn't seem to support bigserial or serial, or have anything in place to specify a primary key w/ auto increment. Any thoughts?
you should make a sequence default value
Navicat Menu -> Others -> Sequence -> (choose table and column) -> save "user_id_plus1"
and set default value for id column with
nextval('user_id_plus1'::regclass)
