Dear Tom,
thanks for your information.
Where can I learn more about the explain and analyze??
One view that is giving a lot of problems is vkardex_3
which is used most of the time...
The explain analyze I sent is one of the views that
conform this one.
Thanks in advance.

Do you really need UNION (as opposed to UNION ALL) in this query?
The EXPLAIN shows that almost half the runtime is going into the
sort/uniq to eliminate duplicates ...
This is one of the queries that work,and is the first
in a 4 level nested query
where do I find how to interpret explains???
thanks in advance,
Carlos.
mate=# explain analyze select * from vdocinvdpre;
