Requesting a PostgreSQL Database

Users can request a PostgreSQL database for their project using this form.

How to Use PosgreSQL 

The psql command line client is available at NERSC on Hopper, and Edison, and can be used to directly connect to a Postgres database via the command line. The system version of the client is 9.1 so if you use this to connect to the NERSC posgres (scidb) servers which are at version 9.4 then you will get a warning. You can get a v9.4 client on Edison by loading the module

module load postgresql 

On a NERSC system, type the following commands to use the psql command line client:

% psql -h yourdb dbuser

Replace yourdb and dbuser with the name of the database and user provided to you by NERSC (request via form above).


Extensive on-line documentation is available.  For questions about PostgreSQL at NERSC, please contact


psql is available on login to Cori and Edison, you do not need to load a module
