Pushing LIMIT into sub-queries of a UNION ALL?

[Dave Johansen <davejohansen@xxxxxxxxx>]

I am using Postgres 8.3 and I have an issue very closely related to the one described here:
http://archives.postgresql.org/pgsql-general/2005-06/msg00488.php



Basically, I have a VIEW which is a UNION ALL of two tables but when
 I do a select on the view using a LIMIT, it scans the entire tables and
 takes significantly longer than writing out the query with the LIMITs 
in the sub-queries themselves. Is there a solution to get the view to 
perform like the sub-query version?

Thanks,
Dave
