Обсуждение: Get a list of databases?

Hello:

My code needs to be able to allow the user to select which
database to connect to.

Is there a programmatic way to get a list of the databases
managed by a pgsql server?

Thanks,
    Neil

You can use the output from following command:

psql -l

try
select datname from pg_database;

I found that setting the ECHO_HIDDEN psql runtime variable to be fairly
informative with something like this.  It basically explains exactly the
queries it runs against the DB to do anything.  Either from the
commandline or in your .psqlrc file:

\set ECHO_HIDDEN TRUE

Then do something mundane like '\d'.

HTH,
