Hi Tom,

Thanks, thought the same, but the current pg_dump and pg_restore versions are as follows:

pg_restore -V
pg_restore (PostgreSQL) 10.16 (Ubuntu 10.16-1.pgdg20.04+1)
pg_dump -V
pg_dump (PostgreSQL) 10.16 (Ubuntu 10.16-1.pgdg20.04+1)

Nothing has been changed since the last week in the postgresql versions, including pg_dump and pg_restore.
I use default OpenProject settings, including PostgreSQL, now same 10.16 for the last couple of months.

Also, to make it more complex,
I have restored with no problem the dump from April 8 [that was a life-saver], made with the same pg_dump as this one used on April 12. The latest, however, cannot be restored.

Best,
Piotr

Full dump created on April 12, 2021, default Ubuntu 18.04 LTS, cannot be
restored on April 19, with the current output:

psql --version
psql (PostgreSQL) 10.16 (Ubuntu 10.16-1.pgdg20.04+1)

pg_restore returns:
pg_restore: [archiver] unsupported version (1.14) in file header

The most obvious explanation for this is that you made the dump
with a v12-or-later pg_dump, and are now trying to restore it
with a pre-v12 pg_restore.  If so, the failure is expected.
