Обсуждение: Permissions and PGSQL
Hi, I use PgSql for a lot of our company's need and I lack some features. I would like to know if there is plans to implement: - User permissions based on columns? (Ex: User1 has Select on Column "CompayName" but User2 has update on column "CompanyName" while User3 has create new row on table). - Permissions on create table. This is the most lacking permission problem actually, since everyone that can log in PgSql can create tables... Thanks to share ideas and on going work. -jec

The CREATE permission on schemas is what you want. Perhaps the CREATE permission on databases as well. You need to revoke these from the public schema. Or even just drop the public schema. Chris

As the previous responder said that is no standard column security. However it should be possible to do something custom to do this using rules and/or triggers.

Well, I have about half a patch for column privileges lying around, but I've never had enough motivation to do the other, more complicated half...

You can do it with views, but it's tedious, and more to the point the
SQL standard says that you're supposed to be able to do it directly.
So I think this should be on TODO. I wouldn't put a real high priority
on it personally, but it's a spec-compliance item ...
