Hello,
There is the following sentence in description of the track_io_timing
parameter:
I/O timing information is displayed in <xref
linkend="pg-stat-database-view">, in the output of <xref
linkend="sql-explain"> when the <literal>BUFFERS</> option is used, and
by <xref linkend="pgstatstatements">.
Is it correct? Shouldn't the TIMING option be mentioned there instead of
BUFFERS?
Best regards,
Alexander

Yes, it's correct. Track_io_timing parameter corresponds to the buffer
manager. With BUFFERS option EXPLAIN shows buffers usage; when
track_io_timing is on it also shows I/O read and write time.
