Enable pg_dump format option.
The format option of pg_dump enables tar and custom archive file formats in addition to the default plain-text file containing SQL commands. When either the tar or custom format are selected the behaviour of database=all is changed to no longer dump a single file via pg_dumpall. Instead pg_dumpall is called once to export the "global" data (roles & tablespaces) and then pg_dump is called once for each non-template table in the database. To support the GZIP and GZIP_OPTS variables in backupninja and to give the default --rsyncable gzip compression flag a chance at working on a PostgreSQL backup, the custom output is forced to not use compression. Instead compression is done via a pipe to gzip. Hopefully this benefits rsync and rdiff-backup style backups for reduced backup and storage costs that outweigh the restoration ones.
