Bug#838080: bacula-director-pgsql: make_catalog_backup fails

[Carsten Leonhardt]

Package: bacula-director-pgsql
Version: 7.4.3+dfsg-6
Severity: serious

XXX_DBUSER_XXX is not replaced by the name of the database user in
make_catalog_backup:

user=${2:-XXX_DBUSER_XXX}

consequently, the catalog backup fails.
