I think the issue is due to my defining the tables using the ansisql engine and then using toengine() to adapt it to postgres. I'll look into it further.
Yep, that's the problem. Column.copy() (and _make_proxy()) both create new Columns w/o passing all the settings of the current instance, i.e. nullable and hidden in the first case, just nullable in the second). Was there a reason for this (read as - is it going to break something elsewhere if these are added)?
