reload_walreceiver_conninfo_v001.patch (text/x-diff) patch v1

Hello all
Now we integrate recovery.conf into GUC system. So i would like to start discussion to make primary_conninfo and primary_slot_name PGC_SIGHUP.
My work-in-progress patch attached.

I think we have no futher reason to have a copy of conninfo and slot name in WalRcvData, so i propose remove these fields from pg_stat_get_wal_receiver() (and pg_stat_wal_receiver view). This data can be accesible now via regular GUC commands.

Thank you for advance!

regards, Sergei
