You didn't show the error message but I suspect it is:

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

As you showed the first bytes in the dump file, that first information (11.18)

is the current Postgres version and the second one (15.2) is the pg_dump

version that you used to create that dump file. Since old pg_dump version might

not read a new format, you are getting this error. You can fix this issue using

the pg_restore from version 15.

Hello Euler,

thank you for your response.

The backup file has generated external enterprise that me.

You said i try import it backup file with pg_restore version 15, its correct?

For a correct import, i need the version Postgree database i must have (11.18) version but i need a pg_restore version 15 for import this "bak file"

Its possible i have install Postgree database (11.18) and parallel i use only a pg_restore version 15?

My sistem is a redhat unix.

This is the header backup file.
