So you can now do any of the following to set the application name:

- Set $PGAPPLICATIONNAME on the client, prior to connection.
- Include 'application_name=MyCoolApp' in the PQconnectdb connection string.
- Use SET application_name

Currently though, pg_dump and psql (and presumably their close
friends) use PQsetdbLogin to establish their connection. Would it be
preferred if I:

a) Added PQsetdbLogin2() with an additional option for the application
name (my guess is 'no').
b) Updated the apps to use PQconnectdb
c) Something else?
