pg_dumpbinary v2.18 released

Grenoble, France – June 22, 2024

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 two bugs in the restore process.

  • Fix double copy statements when a table name requires to be quoted.
  • Fix error when restoring a table with a GENERATED ALWAYS column.

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 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 , 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.
