[ADMIN] new to Linux & Postgresql

[Robb Fenwick]

Hello,   I am new to Linux and Postgresql. I would like to start a database and on installation of Red Hat 7.2 installed SQL server which is Postgres. I do not know where to go from here. I have taken some classes in using SQL usually at the prompt in class I would type "psql myname" and was able to start creating tables. However this is not the case here and I am not sure what to set up or how to get my server going. Can someone please help? Thank you!   RF
