Previously pg_receivexlog created new connection for WAL streaming even though another connection which had been established to create or delete the replication slot was being left. This caused the unused connection to be left uselessly until pg_receivexlog exited. This bug was introduced by the commit d9f38c7. This patch changes pg_receivexlog so that the connection for the replication slot is reused for WAL streaming. Andres Freund, slightly modified by me, reviewed by Michael Paquier
