I don't think so.  He's reimporting the same data he had, so the range
of index entries should have been the same; no reason to expect index
bloat.

Info about the physical size of the index before and after rebuilding
(eg, VACUUM VERBOSE output) would have proved it one way or the other,
but we haven't got that.
