Thanks all -- I made my first post under an unregistered account. It was stalled. Then I posted under my registered account - to which Tom Lane replied (thanks Tom) Then later my first post punched through making it seem like I didn't see Tom Lane's reply. We have some dynamic-schema generation action happening here and are using unions for at least the time-being. Potential perf issues aside, we just wanted to be aware of the limits if there were any. Thanks again.
