Mark application_name as GUC_REPORT so that the value will be reported back
to the client by the server. This might seem pretty pointless but apparentlyit will help pgbouncer, and perhaps other connection poolers. Anyway it'spractically free to do so for the normal use-case where appname is only setin the startup packet --- we're just adding a few more bytes to the initialParameterStatus response packet. Per comments from Marko Kreen.
