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 \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.
