Hi.

The recent commit(7a85073) has redesigned the view pg_stat_subscription_workers
and now we have pg_stat_subscription_stats. Therefore, I rebased my patch
so that my statistics patch can be applied on top of the HEAD.

In the process of this rebase, I had to drop one column
that stored error count for unique errors(which was
incremented after confirming the error is not the same as previous
one), because the commit tentatively removes the same error check
mechanism.

Therefore, this patch has apply_commit_count, apply_rollback_count only.
I slightly changed minor changes as well so that those can
become more aligned.

Kindly please have a look at the patch.
