The latest patch has another problem; pg_receivexlog trying to connect to
the PostgreSQL >= 9.4 always reports the following message unexpectedly.

could not identify system: got 1 rows and 4 fields, expected 1 rows
and 4 or more fields

This problem happens because the patch incorrectly treats the case where
IDENTIFY_SYSTEM command returns NULL as database name, as an error case.

Attached is the updated version of the patch, which fixes the problem.
Comments?

The patch looks good. The top comment of RunIdentifySystem is incorrect though. It should mention that a database name is returned and not a plugin name.
