No the whole thing is in one transaction, which is what I want so that
either all of the data from a particular file gets loaded or none of
it.

Oracle just reports the 'error' back through DBI::errstr and the
script can choose whether to abort the transaction or not. I was
hoping that there might be a way of making Postgres behave the same
way. i.e. The database just reports what happened and the user gets
to decide what constitutes a teminal error.

I had pretty much resigned myself to adding the duplicate checks,
I just wanted to make sure I had not overlooked an option somewhere
before I did so.
