Erwin-
If you created your dump file using the -Fc or -Ft format switches, you'll
need to use pg_restore to restore from the dump file. Without the format
switches, pg_dump creates a plain text file of psql commands.
Generally, I'd say that if you intend to restore the entire contents of your
dump file, then using the plain text format (& compressing with gzip if
needed) is the way to go.
If you need the ability to selectively restore some part of the dump file,
(like one table) then you should use one of the non-text formats for pg_dump
and thus need to restore using pg_restore.
I've learned that doing a complete restore of a non-text dump file using
pg_restore is a real pain, so our backup strategy includes creating both a
tar-format and plain text dump file of the entire database so we are
positioned to do either a partial or full restore with ease.
