RecreateTwoPhaseFile() gets called in the checkpointer or the startup
process which do not have a transaction context so the wait event
would not get cleaned up, and we should call pgstat_report_wait_end()
in the third elog(ERROR), no? It looks that 249cf070 has been rather
inconsistent in its way of handling things.
