Michael Paquier 290bb8afe6 Tighten proto_version parsing in pgoutput ...

This is similar to 58ff4a0a08, but this time for the parameter
"proto_version", when given as a parameter to pgoutput for logical
replication.  strtoul() lacked a check for an empty string, leading to
an inconsistent behavior depending on the platform.

The author has originally proposed a TAP test to check this empty value
pattern.  I have added a cheaper SQL query, instead, test_decoding
including a test area where this is possible.
