Обсуждение: COPY with INDEXES question

Hi,

I have a quick question. In order to speed up insertion of large number of
rows (100s of thousands) I replaced the INSERT with the COPY. This works
fine but one question popped into my mind. Does copy updates indexes on
that table if there are some defined?

Thanks,
Slavisa

Yes, of course.  Runs triggers and stuff as well.

Thanks for the reply and thanks even more for the good one :).

Cheers,

Copy does nearly everything that standard inserts to. RULES are the only
thing that come to mind. Triggers, indexes, constraints, etc. are all
applied.
