Join Bill Weinman for an in-depth discussion in this video Defining a table in SQL, part of PostgreSQL 9 with PHP Essential Training.
Creating a table in Postgres is accomplished with the SQL CREATE TABLE…statement, and it looks like this.…We're here in the SID application, and you'll notice I've got the test database…selected.

And I'm…going to give it a column definition here.…First column will be animal, and that's a text column, and the second column…will be sound, and that is also a text column.…
There are a lot of different column types available in Postgres, and we will…cover what those are and how they work in another chapter.…So I'll go ahead and press the Go button now and lapse time 6 milliseconds, and…that table is now created.…If I try to create the table again, if I press Go again, you'll notice I'll…get an error that that relation, as it calls it, already exists and so it…cannot create that table.…And if I take a look at the tables that are already defined in this database, by…typing SELECT * FROM view_tables;--and this is a view that I've created that's…
