Sometimes CREATE_REPLICATION_SLOT ... LOGICAL ... needs to wait for further WAL using WalSndWaitForWal(). That used to always respect wal_sender_timeout and kill the session when waiting long enough because no feedback/ping messages can be sent while the slot is still being created. Introduce the notion that last_reply_timestamp = 0 means that the walsender currently doesn't need timeout processing to avoid that problem. Use that notion for CREATE_REPLICATION_SLOT ... LOGICAL. Bugreport and initial patch by Steve Singer, revised by me.
