A while ago the some developers inserted several records with a
document (stored in doc_Data) that was around 400 - 450 MB each. Now
when you do a select * (all) from this table you get a hang and the
system becomes unresponsive.

What application/program is "hanging"? The client that retrieves the data or 
PostgreSQL itself?

So I'm not sure how to find these bad records and why I am getting a
hang.
If your client application is hanging, I don't think there is a single "bad" 
record, it just chokes on the size of the result set.

Thomas
