Amit Kapila 7a85073290 Reconsider pg_stat_subscription_workers view. ... It was decided (refer to the Discussion link below) that the stats collector is not an appropriate place to store the error information of subscription workers. This patch changes the pg_stat_subscription_workers view (introduced by commit 8d74fc96db) so that it stores only statistics counters: apply_error_count and sync_error_count, and has one entry for each subscription. The removed error information such as error-XID and the error message would be stored in another way in the future which is more reliable and persistent. After removing these error details, there is no longer any relation information, so the subscription statistics are now a cluster-wide statistics. The patch also changes the view name to pg_stat_subscription_stats since the word "worker" is an implementation detail that we use one worker for one tablesync and one apply.
