Use pg_dump or pg_dumpall.  If you're at the level that you have to ask
this question, then you'll have nothing but trouble getting reliable
backups by backing up directories.

Also, since you're new to PostgreSQL, I _HIGHLY_ recommend that you don't
assume that you're getting backups until you can demonstrate that you can
restore them.
