I have downloaded postgreSQl 9.3 and Postgis 2.1 recently as an educational adventure and have been working with both through the pgAdminIII interface. I haven't used psql yet when working with my simple data sets (.shp and .dbf tables) as I learn my way around both programs, creating databases and tables/views and then working with them in QGIS 2.2 (another open source program i am learning my way around)
My question: Are there advantages of using one over the other (pgAdmin vs psql) or are there certain situations (database/data entry,creation,editing etc) where one should be used over the other?. Or are they essentially both the same and thus a matter of preference?.
I understand that one is a user interface and the other is command line...Much of the open source material is all new to me (both my education/work background are with ESRI products) so excuse the simplicity of my questions.
