Re: Downgrading v8.4 database to v8.3

Dbname = perak
psql file was pg_dumped from v8.4

Trying to restore in v8.3:
postgres@gem:/mnt/d/0/psql$ pg_restore --disable-triggers -d perak
perak-100403_2330.psql
pg_restore: [archiver] unsupported version (1.11) in file header

Second attempt with "-i":
postgres@gem:/mnt/d/0/psql$ pg_restore --disable-triggers -i -d perak
perak-100403_2330.psql
pg_restore: [archiver] unsupported version (1.11) in file header

The database was inserted with records using PHP application developed
on machine using v8.3. It was used for 2 days in machine with v8.4.  I
wish to use this database for further development on the development
machine.
