We use PQconninfoParse to check to ensure we have a new enough libpq
to use application_name, so we can avoid sending it with older libpqs.
If we disable the check for older libpqs, then we'll always get an
error with them. The only way to fix that would be to only allow a 9.0
libpq to be used.

The current code at least allows 8.4 and 9.0 libpqs.
