Thread: Question re how to secure a postgresql 7.1 installation.
I am looking for a way I can make an individual user or group of users be able to have free reign over a specific databasein the postgresql system but not be able to see or modify any other of the databases installed on the system. Does anyone have any docs on how one would go about doing this. I have already found the ability to control access by machinebut I have not as yet found one for users and databases. I know you can use the grant function to give users rights to certain tables but I am looking to give the user rights tothe full database but only to that one database. Thanks in advance. -------------------------------------------------------------------------------- Eric Naujock CCNA, CCDA, A+, Network +, I-Net + Abacus II 5610 Monroe St. Sylvania, Ohio 43560 <http://www.abacusii.com> E-mail - naujocke@abacusii.com Phone - 419-885-0082 X 241 Fax : 419-885-2717 AOL IM: erlic

Does Postgres always automatically rollback transactions when an SQL command fails?
From
Ryan Ho
Date:
In a transaction, should any of the sql statements fail to execute, does Postgres rollback all the previous statements? To my best knowledge, it should but I have observed that on some occasions, half my transaction can get committed, whilethe other half is unsuccessful. Do I need check for failed transactions and enforce a rollback in my code or is it done by the backend automatically? Thanks in advance Ryan

Yes.

Hard to believe. Can you provide some evidence?
