Maybe I've got a brain lock for the moment but what do I do to the list of
connections I have to handle? Since it is used in several functions I cannot
see how to program this without a global variable albeit a static one. What
I need is a mapping of the SQL conenction name to the PGconn structure.

I also wonder if multiple threads should be allowed access to the same
structure, i.e. if one thread opens a new connection should the other one be
allowed to access this too?

BTW libpgeasy does not seem to be able to be used in multi-threading
environments either. Is this library still supported?
