Hi Tom,
Thanks for reaching out. So far, I was able to narrow it down to a problem
when doing a union between two tables, one of them having a varchar column
and the other one having a text column. Adding an explicit cast seems to
have fixed it, but not really sure why yet. I will try to create a simple
repro scenario.
Thanks,
