pg_dumpbinary 2.3 released

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 2.3 was released today. This release fixes the setting of sequences values after restoring data from binary a dump where sequences values from PostgreSQL extensions was not restored.

pg_dumpbinary is useful in some particular 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.
