Subject: [PATCH] Doc: Mention about caveats of --concurrently on reindexdb
 page

The documentation of REINDEX includes a complete description of
CONCURRENTLY and its advantages as well as its disadvantages, but
reindexdb was not really clear about all that.

From discussion with Tom Lane, based on a report from Andrey Klychkov.
