This seems like much ado about very little. The policy will be the same
as it ever was: once beta1 is out, we prefer to avoid forcing an initdb,
but we'll do it if we have to.
In any case, +1 for fixing whatever needs to be fixed now; I expect to
have a fix for the limited-GIN-index-length issue later today, and that
really is also an on-disk format change, though it won't affect short
index entries. ("Short" is TBD; I was thinking of hashing keys longer
than say 128 bytes.)
