dbshell just runs "psql" with the appropriate parameters. psql does
not accept a password on the command-line or in an environment variable
(because it's unsafe, as other users can see the command line), but only

Thus there is just no way to safely feed the password, short of hijacking
the whole standard input of psql or automatically modifying ~/.pgpass (both
possibilities look bad to me)

I would suggest to setup ~/.pgpass if you are really bothered by this.

If you agree with this analysis, then I'll close the bug. If you don't,
then we should reassign this to postgresql-client as a wishlist bug to
ensure psql has a reliable way to be fed a password (like an option to use
a custom password file).
