Ignoring the db part for now, you can do the first part of your request
like this:
CREATE TABLE mytable2 AS SELECT mycol AS newcolname, id, foo AS foo2
FROM mytable WHERE id > 100;
Then pg_dump -t mytable2 and pg_restore, as the rest of this thread indicates.
Note that you'll lose any triggers, indexes, etc. so only use this if
all you really want is the table. Otherwise, it's probably easiest to
pg_dump the whole database and then drop/rename columns in the new
database.
