Thanks for the tips. In pgAdmin III, I can create a table step-by-step by choosing Edit > Object > New Table
But is there a pace for me to past in a block of code that creates the table with just one process? If I click on the SQL icon, a SQL window opens up, and I can past the code into SQL Editor, but I don't know how to "activate" it; pressing ENTER does nothing. I'm following a pgAdmin tutorial, but this page appears to focus on the terminal instead... http://pgadmin.org/docs/1.4/pg/tutorial-table.html
