Consider
delete from CL where CL_id in (i,j,k,...);
If you have hundreds of target values, it might be better to put them in
a temp table and go
delete from CL where CL_id in (select id from temp_table);
The latter should be reasonably quick in 7.4, but be warned that it'll
suck in prior releases.

That is SQL-spec syntax, but we've not gotten around to implementing it.
COPY is a lot faster for bulk inserts.

Huh? You can use COPY FROM STDIN in most of our client libraries,
certainly so with libpq. What are you using?
