Assuming you're in psql just do:

\l

select * from pg_database;

Use the \l command within psql.

With psql, you can use
psql -l

Else see the pg_database table.

If you attach with psql then just use \l

Or this works as well

SELECT datname from pg_database;

Try \? in psql, it will show some really nice commands. \d will show you the
tables, and "\d tablename" will describe the table.

Try \dS and friends to see the system tables.

One of the best ways to see what is going on under the covers to to
run psql --echo-hidden:

--echo-hidden
Echoes the actual queries generated by \d and other
backslash commands. You can use this if you wish to
include similar functionality into your own pro�
grams. This is equivalent to setting the variable
ECHO_HIDDEN from within psql.

Whoever thought to add this to psql is a genius!!!

I guess "psql -l" is better, so you can then choose the DB. :-)
