npgsql - Npgsql2: Fixed a bug where boolean values were being quoted

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


Fixed a bug where boolean values were being quoted which caused problems with edmgen support. Also, fixed a problem
raisedby this modification when using protocol 2: when issuing an execute statement after being prepared the cast
wasn'tbeing issued. It was being sent as execute npgsqlplan1(1) when it should be execute npgsqlplan1(1::bit).
