User based access

From

Hi all,

Would I be correct in saying that there is no way to allow a few users to
have access to a database, but deny others, under Postgresql?

I have scoured the documentation (which draws a blank) and have looked
through other similar questions to this mailing list (which all seem to
have gone unanswered).

I'm not having any problems creating users, or using the pg_hba.conf -
all I want to do is prevent some postgres users from accessing certain
databases...

Cheers,

Paul.

hba_conf has that ability.

On this same note, can you restrict a certain user to just read-only and allow
others to have write access to certain tables. If so, how would I go about this?

Thanks

Hi,

You need to look at the GRANT and REVOKE commands in the SQL documentation.

e.g. to allow harold read-only on table contacts command (run by table
owner) would be similar to:


REVOKE all ON contacts FROM harold;
GRANT select ON contacts TO harold;

and to deny a user access to a table just REVOKE all the privileges from
them.

Regards,

Neil
