Hello
I noticed, that some serial field is using wrong sequence, so I altered
the default value pointing to the sequence I want, but now I cant delete
currently no longer used sequence. Did I do someting wrong changing it?
PgSQL 8.1 on Gentoo Linux.
What I try to do
DROP SEQUENCE b_prekes_br_kodas_pbk_id_seq1;
Result
ERROR: cannot drop sequence b_prekes_br_kodas_pbk_id_seq1 because table
b_prekes_br_kodas column pbk_id requires it
HINT: You may drop table b_prekes_br_kodas column pbk_id instead.
********** Error **********
ERROR: cannot drop sequence b_prekes_br_kodas_pbk_id_seq1 because table
b_prekes_br_kodas column pbk_id requires it

Hint: You may drop table b_prekes_br_kodas column pbk_id instead.

Hello Achilleas.
I think you are wrong on this point - I can create some sequence (the
owner is set) and then drop it easily. I think this is because
b_prekes_br_kodas_pbk_id_seq1 was created automatically creating serial field and is in some way connected to it. Thats why I get error saying "...column pbk_id requires it." Any way I can't find a way to find and alter this dependency.

It's a row in pg_depend. In 8.2 and up you can create/delete the row
with ALTER SEQUENCE OWNED BY, but in earlier releases you'd have to do
it manually.
