LOOKUP JOIN on mixed numerical types #127806
Description
When performing a LOOKUP JOIN on a field which is a float in one index and an integer in another we fail validation in the Join.postAnalysisVerification method. We could consider allowing these mixed types, but we need to add more testing to ensure they do match when expected to match. Ideally the behaviour should conform to the == operator.
The integration tests at #126150 should also be updated to test this case.
