Comment:
I think pwgen is used for both mysql and postgres
```
➜ grep -B2 pwgen ./x2goserver/sbin/x2godbadmin 
	my $dbadmin=$Config->param("postgres.dbadmin");
	my $x2goadmin="x2godbuser";
	my $x2goadminpass=`pwgen -s -c -n 32 1`;
--
	my $dbadmin=$Config->param("mysql.dbadmin");
	my $x2goadmin="x2godbuser";
	my $x2goadminpass=`pwgen 8 1`;
```
