Hi Kevin,
Sorry to disturb you.. But I am really new in it...
Let me see if I understood...
pg_dump -h sourcemachine -U sourceuser source_dbname | psql target_dbname
Is that?
The data will be import in the existing db?

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