When I create a Oracle 11gR2 database we initially use the netca and dbca utilities to create the basic database files and network connections. Afterwards we run a bash script to create the application database detail files. We use this bash script to define certain files on specific raid-1 file systems. How would we do this using PostgreSQL? What is the version of PostgreSQL you would suggest running on RHEL 5.9 x86_64? If I wanted to move from Oracle to PostgreSQL is it possible to use a Oracle export DMP file to load the PostgreSQL database?
