I think those functions really only make sense for physical replication.
Looking at the docs e.g:
https://www.postgresql.org/docs/10/static/logical-replication-monitoring.html
they appear to *suggest* that monitoring should be similar...some
clarification there is probably in order!
However they also say to use the pg_stat_subsubscription view to monitor
your logical rep, e.g: here's what my pgbench dataset subscription looks
like:
bench=# SELECT * FROM pg_stat_subscription;
subid | subname | pid | relid | received_lsn |
last_msg_send_time | last_msg_receipt_time |
latest_end_lsn | latest_end_time

Hi Soumitra,
Could you please explain the reason behind taking the
pg_current_xlog_insert_location() & restart_lsn?
