Postgresql: keep 2 sequences synchronized
- by Giovanni Di Milia
Is there a way to keep 2 sequences synchronized in Postgres?
I mean if I have:
table_A_id_seq = 1
table_B_id_seq = 1
if I execute SELECT nextval('table_A_id_seq'::regclass)
I want that table_B_id_seq takes the same value of table_A_id_seq
and obviously it must be the same on the other side.
I need 2 different sequences because I have to hack some constraints I have in Django (and that I cannot solve there).
