I think you have omitted a bunch of relevant facts.  Bare INSERT is
reasonably quick:

regression=# create table foo (f1 int);
CREATE TABLE
regression=# \timing
Timing is on.
regression=# insert into foo select x from generate_series(1,200000) x;
INSERT 0 200000
Time: 5158.564 ms
regression=# 

(this on a not-very-fast machine) but if you weigh it down with a ton
of index updates, foreign key checks, etc, it could get slow ...
also you haven't mentioned what else that plpgsql function is doing.
