You can use the INFORMATION_SCHEMA (which is standard SQL), but in psql
the simplest way is:

  \d+           Show all tables, with descriptions
  \d+ table     Show the definition of the named table (or view), with
                  column descriptions

  \?            Describe briefly all the \ commands in psql

The capabilities of psql are fully described in the manual and in psql's
man page.
