Make local copy of client hostnames in backend status array.
The other strings, application_name and query string, were snapshotted tolocal memory in pgstat_read_current_status(), but we forgot to do that forclient hostnames. As a result, the client hostname would appear to change inthe local copy, if the client disconnected.Backpatch to all supported versions.Author: Edmund HornerReviewed-by: Michael PaquierDiscussion:https://www.postgresql.org/message-id/CAMyN-kA7aOJzBmrYFdXcc7Z0NmW%2B5jBaf_m%3D_-77uRNyKC9r%3DA%40mail.gmail.com
