Look again --- you seem to have invoked "postgres", not "psql". There
is seldom any reason to invoke the "postgres" program directly.
If you really did type "psql" then your installation is messed up
(somehow postgres got copied over psql, I suppose). Might be easiest
to remove and reinstall the programs.
