Обсуждение: Listing databases
Sorry for the newbie question, but how do you get PostgreSQL to list the available databases? I know how to log into a certain database, but not list all of them. I know this must be possible because the phppgAdmin web site demonstrates it with their trial server. Thanks, Doug Hall

Assuming you're in psql just do: \l

With psql, you can use psql -l Else see the pg_database table. -- Alvaro Herrera (<alvherre[a]dcc.uchile.cl>) "En las profundidades de nuestro inconsciente hay una obsesiva necesidad de un universo lógico y coherente.

If you attach with psql then just use \l Or this works as well SELECT datname from pg_database; > Sorry for the newbie question, but how do you get PostgreSQL to list > the available databases?

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!!! HTH... Mark -- Mark Harrison Pixar Animation Studios

I guess "psql -l" is better, so you can then choose the DB. :-) -- 19:10:02 up 7 days, 32 min, 1 user, load average: 0.60, 1.02, 1.38 ----------------------------------------------------------------- Martín Marqués | select 'mmarques' || '@' || 'unl.edu.ar' Centro de Telematica | DBA, Programador, Administrador Universidad Nacional del Litoral -----------------------------------------------------------------
