I think this is the same issue that Stephan identified in his response
to your other posting ("sub-select with aggregate"). When you write
FROM x join y using (col) WHERE x.col = const
the WHERE-restriction is only applied to x. I'm afraid you'll need
to write
FROM x join y using (col) WHERE x.col = const AND y.col = const
Ideally you should be able to write just
FROM x join y using (col) WHERE col = const
but I think that will be taken the same as "x.col = const" :-(
