Thanks Richard,
I went through dblink and tried it . But I am not able to pass variables to
sql stmt of dblink_exec function . Basically If I hardcode the values for
updating a table for the sql statement in different database it is working
fine. But What I wanted to do is get the info from existing modified row and
pass that into the update query which I am writing inside dblink_exec call.
my sql inside dblink_exec call would look like
UPDATE my_table set myotherDBTableField = NEW.currDBTableField WHERE
{condition}
When the trigger function executes this it is giving an error some Rule need
to be set.
Whereas If I hardcode that value instead of using NEW.xxxx it is working fine?
I appreciate any insights,
thanks,

Sure - check the manuals (in 8.3) for dblink - it's in contrib. It's
been there for a while, but the documentation for contrib modules wasn't
in the manual until 8.3
