Sounds like you didn't read up on pg_dump to closely.

What you probaly should have doe was not use pg_dumpall, but
pg_dump -o -F t livedb > livedb.dump.tar

The use pg_restore

My distribution doesnt have pg_dumpall, but I imagine that unlike pg_dump
where it does

\connect - someuser

at the top.

It does
\connect origdb someuser

So you probably want to edit a copy of the dump file,
remove the db nmae from the connect statement, then drop the old db
then

You should be able to execute that section of the dump pertaining to the
db you want to restore on the replacement original, and the new database.

EG:

Your edited snippet of the dump (Checcking all \connect statements to
ensure they are eiter removed, or refer to currently connected
database (-) is in dbdump.sql

psql -U username
