Why not? Just do something like this:
CREATE TEMPORARY TABLE tmp (col1 TEXT NOT NULL, col2 INTEGER NOT NULL);
COPY tmp FROM STDIN;
row1 1
row2 2
...
\.
INSERT INTO target SELECT * FROM tmp;
If you need some kind of SELECT/INSERT/UPDATE cycle, it's far more
complex, of course, and I'm not quite happy with what I'm using right
now.
