Selects the format of the dump output. DumpFormat can be one of the following:
Parameters:
dfPlain
Output a plain-text SQL script file (default)
dfTarArchive
Output a tar archive suitable for input into TPSQLRestore or pg_restore. Using this archive format allows reordering and/or exclusion of database objects at the time the database is restored. It is also possible to limit which data is reloaded at restore time.
dfCompressedArchive
Output a custom archive suitable for input into TPSQLRestore or pg_restore. This is the most flexible format in that it allows reordering of loading data as well as object definitions. This format is also compressed by default.
dfDirectory
Output a directory-format archive suitable for input into pg_restore or TPSQLRestore. This will create a directory with one file for each table
and blob being dumped, plus a so-called Table of Contents file describing the dumped objects in a machine-readable format that TPSQLRestore and pg_restore
can read. This format is compressed by default.
