>Hi Folks,
>We are setting up a Linux server, Red Hat 9, and will be installing PostgreSQL on it. A VFP front end will access the PostgresSQL from Windows clients. My question is are there Windows GUI dba tools that I can use to work with the Linux PostgreSQL or do I need to have a Linux Client to use the GUI interfaces for managing the LINUX PostgreSQL database? TIA.
