Thread: pgsql: Track statistics for streaming of changes from ReorderBuffer.
Track statistics for streaming of changes from ReorderBuffer. This adds the statistics about transactions streamed to the decoding output plugin from ReorderBuffer. Users can query the pg_stat_replication_slots view to check these stats and call pg_stat_reset_replication_slot to reset the stats of a particular slot. Users can pass NULL in pg_stat_reset_replication_slot to reset stats of all the slots. Commit 9868167500 has added the basic infrastructure to capture the stats of slot and this commit extends the statistics collector to track additional information about slots. Bump the catversion as we have added new columns in the catalog entry.
