Recently pgpool-II introduces its own regression test framework
written in shell script which can create a streaming replication
primary and arbitrary number of standbys in single server. The test
scenarios are written in a shell script, thus is reasonably
flexible. I have read through all the thread but I am not sure how to
reproduce the problem reliably. If I would know it, probably I can
integrate into the regression test.

Agreed. I think this is very critical for us.
