Hi all,
While working on REINDEX CONCURRENTLY, I have noticed that
index_build() does not need its argument isprimary. Perhaps it is
not worth bothering, but for the REINDEX CONCURRENTLY business this
removes the need to open an index when triggering a concurrent
build.
The flag was introduced in 3fdeb189, but f66e8bf actually forgot to
finish the cleanup as index_update_stats() has simplified its
interface.
Are there any objections if I cleanup that stuff as per the attached?
Thanks,
--
Michael
