Hello Jaime, Thank you for the test cases!

I am able to duplicate the error you saw in the uint_test2.sql. I am assuming you are seeing this error in the uint_test1.sql: ERROR: could not find hash function for hash operator 16524 I can bypass the error in uint_test1.sql by disabling the hash joins. I am going to dig in and figure out why the hashjoin operation is broken. Just wanted to give you an update that I was able to reproduce the error with your test cases and I am working on a solution now.
