Handle PostgreSQL notifications early, fix #311.

Browse Source 
In some cases, like when client_min_messages is set to debug5,
PostgreSQL might send notification messages to the connecting client
even while opening a connection. Those are still considered WARNINGs by
the Postmodern driver...

Handle those warnings by just printing them out in the pgloader logs,
rather than considering those conditions as hard failures (signaling a
db-connection-error).
