Well, the full text is:
Allow the retrieval of statistics from foreign data wrapper servers
(Corey Huinker, Etsuro Fujita) §
This is enabled for postgres_fdw by using the option restore_stats. The
default is for ANALYZE to retrieve rows from the remote server to
locally generate statistics.
It clearly mentions in the detail that it applies only to postgres_fdw,
so I think it is already in the right section. While it technically can
be done by any FDW, it is now only postgres_fdw so people looking for
postgres_fdw improvements will find it in the Additional Modules
section. What we can do is to reword it to:
--> Allow the retrieval of statistics from postgres_fdw foreign data
wrapper servers
(Corey Huinker, Etsuro Fujita) §
--> This is enabled by using the option restore_stats. The
default is for ANALYZE to retrieve rows from the remote server to
locally generate statistics.
but I think this is worse because it sounds like it can _only_ ever be
done by postgres_fdw. However, if you prefer this I will make this
change.
I avoided "General Performance" because frankly, it is only
postgres_fdw, and it not a "General" performance improvement, and we
have a section for postgres_fdw already.
