what evidence do you have that you are suffering index bloat?

The files for the two indices on a single table used 7.8GB of space before a reindex, and 4.4GB after.

That's not bloat ... that's pretty nearly in line with the normal
expectation for a btree index, which is about 2/3rds fill factor.
If the compacted index were 10X smaller then I'd agree that you have
a bloat problem.
I wrote "I don't think this counts as bloat...".  I still don't.
