bacula-director-pgsql does not install cleanly with db-config

Binary package hint: bacula-director-pgsql

The package postinst script (through db-config) does not set template database properly and thus the database creation fails:

Creating config file /etc/dbconfig-common/bacula-director-pgsql.conf with new version
creating postgres user bacula: success.
verifying creation of user: success.
creating database bacula: failed.
error encountered creating database:
ERROR: new encoding (SQL_ASCII) is incompatible with the encoding of the template database (UTF8) HINT: Use the same encoding as in the template database, or use template0 as template.
dbconfig-common: bacula-director-pgsql configure: ignoring errors from here forwards

The bacula database should be set to SQL_ASCII, as evidenced here: http://www.bacula.org/5.0.x-manuals/en/main/main/Installing_Configuring_Post.html#SECTION004220000000000000000

Steps to repeat:

1. Install postrgesql server
2. Install bacula-director-pgsql
3. Select configure the database via dbconfig
