Restoring to a new database should not put the data in pre-existing
databases at risk. I wouldn't recommend the tar format for your
dump, though -- I've had better luck with custom if I want a
"structured" dump from which I can selectively restore. If you want
the whole thing, and don't need an intermediate copy (two big "ifs",
I know), you could do something like this on the target machine:
pg_dump -h sourcemachine -U sourceuser dbname | psql dbname
-Kevin
