# Script to generate schemas for the various versions.

# Some setup is required, similar to the opportunistic tests.

# MariaDB [(none)]> CREATE DATABASE keystone
# MariaDB [(none)]> GRANT ALL PRIVILEGES ON keystone.* TO 'keystone'@'localhost' IDENTIFIED BY 'password';
# MariaDB [(none)]> quit;

# Postgres ->

# $ sudo -u postgres psql
# postgres=# create user keystone with createdb login password 'password';
# postgres=# create database keystone with owner keystone;
# postgres=# quit;
#
# Note that you may also have to configure 'pg_hba.conf' to use password-based
# auth instead of "ident", if you haven't done so already. You can locate this
# with 'locate pg_hba.conf'. More details at
