Specifies in what format dump file was stored.
Specify format of the archive. It is not necessary to specify the format, since TPSQLRestore will determine the format automatically. If specified, it can be one of the following:
Format auto determination. Default value.
The archive is a tar archive. Using this archive format allows reordering and/or exclusion of schema elements at the time the database is restored. It is also possible to limit which data is reloaded at restore time.
The archive is in the custom format of pg_dump and TPSQLDump. This is the most flexible format in that it allows reordering of data load as well as schema elements. This format is also compressed by default.
