pg_dumpbinary dumps a PostgreSQL database to a binary format. The resulting dump must be restored
using pg_restorebinary, which is provided.
pg_dumpbinary 2.14 was released today, it adds two new options and fixes some bugs reported by users since last release.
--with-child, when -t or -T options are used, to include or exclude child and partition tables. pg_dump will be used instead with options --table-and-children or --exclude-table-and-children. It requires PostgreSQL >= 16.-V, --verbose option that lists tables included in the dump.-A, --attach SNAPSHOT to be able to attach pg_dumpbinary to an existing snapshot instead of creating a dedicated one.A full list of changes and acknowledgments can be found here
pg_dumpbinary is useful when:
pg_dump because the
total size of the escape/hex output exceeds 1Gb.\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.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.
