Thanks. I agree that it still useful to write more complex
tests. The most significant issue on this (PsqlSession.pm) comes
from the fact that I didn't find the way to detect the end of an
query execution without attaching a bogus query.. And this kind
of things tend to be unstable on an high-load environment.
