I think this needs some adjustment: IIUC the new feature in PG17's
295c36c0 is that we now also track (and show) timings for local
blocks. I/O timings on shared and temp blocks were already tracked
(and displayed with the BUFFERS option) when track_io_timing was
enabled: temp timing was introduced with efb0ef90 in early April 2022,
and the output of IO timings for shared blocks has existed since the
introduction of track_io_timing in 40b9b957 back in late March of
2012.

Kind regards,
