/me has started working on hierarchical query support that I'd like to get into 8.2.

Possibly you could define that as "all columns that are not specified in
the INSERT command and have column default expressions".  The first is
knowable with very little parsing of the command, and the second can be
learned from the catalog metadata that you're probably reading anyway.

If the JDBC spec has a more specific definition of "autogenerated" than
"has a default", then what is it?
