Fix comparison of numeric jsonb columns

[erikdubbelboer]

Since we use ->> on jsonb fields we always get a string back. Comparisons such as < and > were done on string values which gives unexpected results.

I have tried various other approaches that failed.

• Casting everything to a jsonb doesn't work because you can't cast query params to jsonb.
• Using a CASE WHEN with jsonb_typeof doesn't work because each WHEN of a CASE WHEN needs to return the same type.
• There are also complications with calling Convert recursively for $elemMatch where you then don't know the column type anymore.
