Short Description
Granting insert on a table does not grant update to the ralated sequence

Long Description
I recently upgrated to PostgreSQL 7.1.3 from 7.0.something (I don't remember exactly)

I dumped my databases, intstalled PostgreSQL v 7.1.3 and created my databases from the text-dump. The users privileges were allready set-up correctly on the tables. But everytime a user -other than the db owner- tried to insert a row in a table in witch he had append permission he got an error message. The reason: he had no update privilegde to the sometable_id_seq. ('id' in my case is an autoincrementing integer just to identify the row). I solved it so:

somedb# GRANT UPDATE ON sometable_id_seq TO someuser ;

but I think that this must be granted automaticaly when I grant insert to someuser on sometable.
