Mmmh, I actually looked into that but I thought it
only worked with user functions...
am I wrong?

What I'd like to have is an almost-transparent
horizontal partitioning system, and
I think that everything is there: postgresql
partitioning (which even has partition pruning)
 + dblink should be enough...

it's only that you can't use them together, because
with dblink you should use
VIEWs but partitioning can't work with those (which I
find correct, BTW).
What I would like is for Postgresql to know that a
table is actually a remote table...

BUT!!!
since "Views in PostgreSQL are implemented using the
rule system", I could do
(pseudo-sql)

CREATE TABLE mypartion HINERITS blabla CHECK
CONSTR..[...] ;

CREATE RULE "_RETURN" AS ON SELECT TO myview DO
INSTEAD
    SELECT * FROM dblink;

Can't I??? That would be horizontal partitioning using
dblink+postgresql!!!

Am I wrong???
