I am a pretty heavy user of psql but I don't think that that would be so 
helpful.  I assume you mean a new option, let's call it "\X" the causes 
the next query to be expanded.  I type "\X" then a query.  I realize 
that I made a mistake and have to redo the query so I have to type "\X" 
again.  If I forget then I have to run the query yet again.

What would be useful for me is a control that causes every query to be 
expanded if it returns exactly one row.  Now I can do this:

SELECT * FROM table WHERE table_status = 1; % get a short list
SELECT * FROM table WHERE table_id = 123; % drill down to one ID

The first would give me a normal list and the second would give me an 
expanded look at the one I want to see in detail.
