It is quite typical, yes. It is the base query of a view. In fact, most
views have a lot more joins (they join with all the upper-level tables).
But 150ms is OK, indeed.
If the query using the view does anything more than a "SELECT * FROM
view", you should do an explain analyze of the query instead of the
definition of the view. The access plan might look very different.
The views are used as linked tables in an Access Frontend.
Some accesses are "select * from view", others might filter
on a country_id or something similar.
For the moment performance is good, so I think I'll keep a
normalized database as long as it is possible !
Thanks for your help Heikki !
