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

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
