-q, --quiet

-i, --interactive
Prompt for confirmation before actually removing the user.
username

This name must exist in the PostgreSQL installation.
You will be prompted for a name if none is specified on the command line.
The options -h, -p, and -e,

psql options -U and -W

All is well.
dropuser: deletion of user "username" failed
Something went wrong. The user was not removed.
If there is an error condition, the backend error message will be displayed.
See
and for possibilities.
Description
dropuser removes an existing
PostgreSQL user
and the databases which that user owned.
Only users with usesuper set in
the pg_shadow table can destroy
PostgreSQL users.
dropuser is a shell script wrapper around the
SQL command
via
the PostgreSQL interactive terminal
. Thus, there is nothing
special about removing users via this or other methods. This means
that the psql must be found by the script and that
a database server is running at the targeted host. Also, any default
settings and environment variables available to psql
and the libpq front-end library do apply.
Usage
To remove user joe from the default database
server:
$ dropuser joe
DROP USER
To remove user joe using the postmaster on host
eden, port 5000, with verification and a peek at the underlying
query:
$ dropuser -p 5000 -h eden -i -e joe
User "joe" and any owned databases will be permanently deleted.
Are you sure? (y/n) y
DROP USER "joe"
