A usual reason why I would want to dump everything except for a few
tables is that those few tables are particularly enormous and
particularly useless (at least, for the purposes of my dump).

In that case, the LAST thing I want to do is to make extra copies of
the *useless* tables.

By the way, it is quite likely that the above approach would be more
quickly accomplished via using originaldb as a template for testdb.


$ createdb --template=originaldb testdb
$ for tables in t1 t2 t3 t4 t4; do
> psql -d testdb -c "drop table public.t1;"
$ pg_dump testdb > dumpfile
$ dropdb testdb
