They are mirrored to each other, I beleive. So just different transports
of the same data.

Postgres or PostgreSQL, please, no such thing as postgre.

Not directly. But what you can do is use a server side cursor, and then
fetch one (or a couple) of rows at a time. It should give you
approximatly the same result. See
