Yes, define it as money. Even supports foreign stuff, I think.

Yes, but you have to use parens if you use more than one ||. This is
because of the type-extensibility features.
select (a || b) || c.

Not sure.

Everyone I heard loves psql. \e lets you edit the query, or up-arrow.

Not sure, but I have heard of some.
