Обсуждение: limiting \l [list all databases]

Greetings!

 I apologize if this has been previously posted..

 I run a server with multiple clients running databases on one server,
and I was wondering if there was a way to limit the list all databases
function within the pgsql program to only list databases within a
criteria, say, what they have permission to see?

  Or perhaps, if that is not possible, a way to shut off the
functionality entirely, from the server side?

  Thanks so much!

Justin

It is not possible.  pg_database is a global table, visible to all
databases.  I can't think of a way to limit such visibility.  Perhaps
you can create a pg_database in the public schema and have it only
return the current database and template1.  That might work, or it might
not, but the pg_database will still be visible in pg_catalog.
