# File: pgsql-dropuser.sh
# Changes:
# 20010224 Luca De Vitis <luca@debian.org>
# 20020116 Ola Lundqvist <opal@debian.org>
# Documented the error variable.
# 20041002 Raphaël Enrici <blacknoz@club-internet.fr>
# Quoted $dbuser so that the username can contain '-'.
# 20040322 Ola Lundqvist <opal@debian.org>
# Added use_dbuser=false after pgsql.get as suggested by
# Uwe Steinmann <uwe@steinmann.cx>.
# Needs: $dbuser - the user name to drop
# $dbname - the database that user should have access to.
# $dbpass - the password to use.
# $dbserver - the server to connect to.
# $dbadmin - the administrator name.
# $dbadmpass - the administrator password (not supported).
# which
# pgsql
# /usr/share/wwwconfig-common/pgsql.get
# Description: Drops a user.
# Sets: $status = {error, nothing, drop}
# $error = error message (if status = error).
