Diagnostics

In case of difficulty, see DROP ROLE and psql for discussions of potential problems and error messages. The database server must be running at the targeted host. Also, any default connection settings and environment variables used by the libpq front-end library will apply.

Examples

To remove user joe from the default database server:

$ dropuser joe
DROP ROLE

To remove user joe using the server on host eden, port 5000, with verification and a peek at the underlying command:

$ dropuser -p 5000 -h eden -i -e joe
Role "joe" will be permanently removed.
