I just applied a doc patch for pg_last_xact_replay_timestamp, and the
text now says:
<entry>Get timestamp of last transaction replayed during recovery.
This is the time at which the commit or abort WAL record for that
transaction was generated on the primary.
If no transactions have been replayed during recovery, this function
returns NULL. Otherwise, if recovery is still in progress this will
increase monotonically. If recovery has completed then this value will
remain static at the value of the last transaction applied during that
recovery. When the server has been started normally without recovery
the function returns NULL.
Is this really the last commit/abort record or the last WAL record?
What should it be? Is the name of this function correct? Do we care
only about commit/abort records? Why?
