But this is a problem you have no matter the solution to load the data,
right? Since you work with a partitioned table, you have the same schemas
for all counties. Once you have normalised the format, you can load it
into a staging table and work from there.

Did you actually try it? With proper indexing this does not have to be
that painful.

Then again, if you have code to normalise the data for 3077 counties, I
guess 50 tables with a total of 3077 partitions is a smaller headache.
