Make standby promotion reset the recovery pause state to 'not paused'.
If a promotion is triggered while recovery is paused, the paused state endsand promotion continues. But previously in that casepg_get_wal_replay_pause_state() returned 'paused' wrongly while a promotionwas ongoing.This commit changes a standby promotion so that it marks the recoverypause state as 'not paused' when it's triggered, to fix the issue.Author: Fujii MasaoReviewed-by: Dilip Kumar, Kyotaro HoriguchiDiscussion:https://postgr.es/m/f706876c-4894-0ba5-6f4d-79803eeea21b@oss.nttdata.com
