I'm not sure where we're sitting with this, but I've got another idea I
haven't seen (one that I think is better than an arbitrary limit on the
number of indexes)... what if we just disallow non-concurrent index
builds on hot tables? It sounds like the additional pain involved in
chilling an entire table and keeping it chilled for the index build is
even more overhead than just doing a concurrent index build.
