Hi,
When --buffer-usage-limit option is specified, vacuumdb issues VACUUM or
VACUUM ANALYZE command with BUFFER_USAGE_LIMIT option. Also if
--buffer-usage-limit and -Z options are specified, vacuumdb should issue
ANALYZE command with BUFFER_USAGE_LIMIT option. But it does not. That
is, vacuumdb -Z seems to fail to handle --buffer-usage-limit option.
This seems a bug.
You can see my patch in the attached file and how it works by adding -e
option in vacuumdb.
