Yes, and that is indeed what I see when I run your exampl
Hi,
http://www.postgresql.org/docs/current/static/sql-update.html
has an example where an either an insert or update is done according if
a key already exists.
The example is about wines. I did it with numbers.
drop table if exists tbl;
create table tbl ( key int primary key, val int );
insert
