tablename = "data_%s" % index_name # dynamic table name

Is there a reason the table name must be prefixed with data_? Can we allow complete customisation?

I also would like to know the answer to this, or at the very least have this documented directly within the library. Data is one of those variable names that don't mean anything and this convention forces people to go around what they might already have in their existing pg database. If I steel man the existing implementation, my only guess would be that this is desired b/c of the auto-table generation behaviour, but it shouldn't be necessary. We should be able to trust developers to chose non-overlapping table names.

I honestly don't know why its here either, but since its there now, removing it needs to be done with care -- handling backwards compatibility

I welcome a PR
