Wait ... is the step regarding the Postgres DB listed at

http://wiki.x2go.org/doku.php/wiki:advanced:x2gobroker:loadbalancing

and

http://wiki.x2go.org/doku.php/wiki:advanced:multi-node:x2goserver-pgsql

required even for the python broker?

If so:
a) Would it be possible to install the database server on one of the
   X2Go server nodes?
b) How can it be avoided that this database server becomes a single
   point of failure?  Does Postgres support replication in a multi-
   master way, so the database could reside on each node and they'd
   sync their state?
