as a pgsql superuser, how can i list all the users and their rights? on
mysql i just do a select on the mysql table. i'm a newbie here. i read the
documents and didn't find the answer.
also, when i start 'psql' as system user joe, it says:
psql: FATAL 1: Database "joe" does not exist in the system catalog.
if i run psql as system user XXX it would say '... Database "XXX" does not
exist...'
from the documents, it seems as though i can start psql without specifying
a database.
