This is called when ANALYZE command is executed. (ANALYZE
command should be executed because autovacuum does not analyze foreign
tables.)
This is a good idea.
However, if adding these statistics requires an explicit ANALYZE
command, then we should also have a command for resetting the
collected statistics -- to get it back into the un-analyzed state.
Why would you want this? If the stats aren't up to date, run ANALYZE
periodically. Remember that it is part of the DBA maintenance tasks [1].
