You have to create a database (datafile) first and fill it with tables etc

Omnis connects to the server and you create and open a database on the Postgresql server.

Do not bother using PGAdmin until you really need it. It is a just another tool.

Most stuff can be done from within Omnis using SQL commands. Try to ask more specific because the subject is that big (IMHO).

Learning SQL i fun but a real challenge. You can do more stuff safer and faster than with the native data file. I found this resources valuable: (like this list but bigger) (search this list)
