The following documentation comment has been logged on the website:
Page: https://www.postgresql.org/docs/14/indexes-index-only-scans.html
Description:
11.9.2 lists ```SELECT x FROM tab WHERE x = 'key' AND z < 42;``` as both
examples of 'could' and 'could not' use index-only scans. I believe this is
what was meant:
"""""""""""""""""""
but these queries could not:
SELECT x, z FROM tab WHERE x = 'key';
SELECT x FROM tab WHERE x = 'key' AND z < 42;
"""""""""""""""""""
should read:
"""""""""""""""""""
but these queries could not:
SELECT x, z FROM tab WHERE x = 'key';
SELECT z FROM tab WHERE x = 'key' AND z < 42;
"""""""""""""""""""
