I can believe that MySQL is faster, because they probably don't need
to do the bitmap heap scan. There is a much-anticipated feature
called index-only scans that we don't have yet in PG, which would help
cases like this a great deal.
But I don't see how MySQL could send back 116,000 rows to the client
in milliseconds, or sort them that quickly.
