I have reviewed the latest version and made a few changes along with
fixing some of the pending comments by Peter Smith. The changes are as
follows: (a) Removed m_databaseid in PgStat_MsgSubscriptionError as
that is not required now; (b) changed the struct name
PgStat_MsgSubscriptionPurge to PgStat_MsgSubscriptionDrop to make it
similar to DropDb; (c) changed the view name to
pg_stat_subscription_stats, we can reconsider it in future if there is
a consensus on some other name, accordingly changed the reset function
name to pg_stat_reset_subscription_stats; (d) moved some of the newly
added subscription stats functions adjacent to slots to main the
consistency in code; (e) changed comments at few places; (f) added
LATERAL back to system_views query as we refer pg_subscription's oid
in the function call, previously that was not clear.

Do let me know what you think of the attached?
