OK, so either patch PAF yourself (not recommended) or choose something
else. Note that two other ways are working with Pacemaker:
* the pgsql resource agent (see FAQ of PAF)
* a shared disk architecture (no pgsql replication)

I suppose you could find fencing agents for:

* the blade itself, but it would fence all the container running on it
* the access to the SAN from the failing container

I don't know if fencing agent exists for a container itself. Note that I'm not
familiar with the container world, I lack a lot of knowledge on this
technology.
