## pg_dumpbinary

`pg_dumpbinary` dumps a PostgreSQL database to a binary format. The resulting dump must be restored
using `pg_restorebinary`, which is provided.

This is a maintenance release that fixes some issues reported by users since last
release and adds an new command line option to the `pg_restorebinary` command.

* Add `-V, --verbose` option to `pg_restorebinary`.
* Change directory to writable one when sudo -u is used to avoid
  pg_restore to complain about "could not change directory" when
  the current directory is not writable by the running user. In
  this case `pg_dumpbinary` and `pg_restorebinary` will require an
  absolute path respectively for output and input directory.
*  Do not import the `tmpdir()` method when importing File::Spec.
* Fix returned error code when no input directory or missing parameters.

`pg_dumpbinary` is useful when:

* You have bytea that can not be exported by `pg_dump` because the
  total size of the escape/hex output exceeds 1Gb.
* You have custom type that stores `\0` internally in bytea but data
  are exported by pg_dump as char/varchar/text.  In this case pg_dump
  truncates all data after the first `\0`, resulting in data loss.
* Other cases where a binary output format is useful.

In these kinds of cases `pg_dumpbinary` helps by dumping the
PostgreSQL database in a binary format. In all other cases
the pg_dump/pg_restore commands distributed with PostgreSQL are
preferred.

See the documentation for a more complete description of available
features.
