pg_dumpbinary is a program used to dump a PostgreSQL database with
data dumped in binary format. The resulting dump must be restored
pg_restorebinary that is provided with this tool.
pg_dumpbinary 2.4 was released today, this new release adds a new
command line option to
--truncate to be able to
empty the tables before restoring data. This can be helpful when
pg_restorebinary is used to refresh data from some tables.
pg_dumpbinary is useful in some situations:
pg_dumpbecause the total size of the escape/hex output exceed 1Gb.
\0internally 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.
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.
pg_dumpbinary is an open project from LzLabs GmbH. Any contribution to build a better tool is welcome. You just have to send your ideas, features requests or patches using the GitHub tools.
