Doc: Mention about caveats of --concurrently on reindexdb page

michaelpq · michaelpq · commit 9b60c4b979bc · 2020-05-31T10:48:21.000+09:00
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. Discussion: https://postgr.es/m/1590486572.205117372@f500.i.mail.ru Backpatch-through: 12
