Thread: npgsql - Npgsql2: [#1010986] Endless recursion on hanging connection in

Log Message:
-----------

[#1010986] Endless recursion on hanging connection in ProcessBackendResponsesEnum. Thanks Gildas for feedback and
tests.

Also added a better check in NpgsqlConnector.IsValid(). Now it generates a random number and checks the select return
valueto see if everything is ok. Should fix problems where Npgsql was returning connectors in wrong state.
