PFA patches:

1) v20260316-0001-Report-downstream-sent-bytes-in-pg_stat_replication_.patch:

This patch introduces sent_bytes to report the amount of data sent
downstream. It documents sent_bytes in a way that it clarifies how
sent_bytes differs from total_bytes, without modifying the existing
documentation for total_bytes or total_txns. The patch is purely
additive and does not alter any existing documentation.

2) v20260316-0002-Report-output-plugin-statistics-in-pg_stat_replicati.patch:

This patch adds a couple of more metrics to report the amount of
changes filtered out by the output plugin, as well as the total number
of transactions sent downstream.
