I feel like we just saw this issue earlier.  Why is pandas forcing
indexes to be created?    As I recall mentioning elsewhere, there
should be options on the Pandas side to disable the creation of
indexes.

you can also try providing SQLCompiler.visit_create_index() and
visit_drop_index()  methods that deliver a SQL phrases which do
nothing (or perhaps includes a comment that a CREATE /DROP INDEX is
being skipped).
