## pg_dumpbinary
`pg_dumpbinary` is a program used to dump a PostgreSQL database with
data dumped in binary format. The resulting dump must be restored
using `pg_restorebinary` that is provided with this tool.
pg_dumpbinary v2.10 was released today, it adds a new option to the
pg_dumpbinary command:
* -C, --compress-level 0-9 : speed of the gzip compression using the specified
digit, between 1 and 9, default to 6. Setting it
to 0 disable the compression.
This option can be helpful to speed the export when the majority of the data
don't compress well.
It also fixes several issues reported since last release.

`pg_dumpbinary` is useful in some situations:
* you have bytea that can not be exported by `pg_dump` because the
total size of the escape/hex output exceed 1Gb.
* you have custom type that stores `\0` internally in bytea but data
are returned as char/varchar/text which truncate data after
the '\0'. In this case pg_dump will export data in the output
type which will result in data lost.
* any other case where binary format can be useful.
If you are in this case `pg_dumpbinary` will help you by dumping the
PostgreSQL database in binary format. In all other cases you must
use the pg_dump/pg_restore commands distributed with PostgreSQL.
See documentation for a complete description of the features.
