Thread: Suspicious description of track_io_timing
The following documentation comment has been logged on the website: Page: https://www.postgresql.org/docs/9.6/static/runtime-config-statistics.html Description: 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?

With BUFFERS option EXPLAIN shows buffers usage; when track_io_timing is on it also shows I/O read and write time.
