If a connection committed or rolled back any transactions within a PGSTAT_STAT_INTERVAL pacing interval without accessing any tables, the reporting of those statistics would be held up until the connection closed or until it ended a PGSTAT_STAT_INTERVAL interval in which it had accessed a table. This could result in under- reporting of transactions for an extended period, followed by a spike in reported transactions. While this is arguably a bug, the impact is minimal, primarily affecting, and being affected by, monitoring software. It might cause more confusion than benefit to change the existing behavior in released stable branches, so apply only to master and the 9.4 beta.
