PostgreSQL version: 14.7
Operating system: Red Hat 7.3.1-6 64-bit
Description:

I have an issue that takes place during restore of a 14.4 database. During
this process creation of extension aws_s3 fails because it depends on
plpgsql extension which it seems to be created later on. These are the
commands we use for dump / restore:

pg_dump -d \$DATABASE_URL -j 8 -Z 0 -Fd -f ${backupDir}
pg_restore --verbose --clean --no-owner -d \$DATABASE_URL -j 8 --format=d
${backupDir}

This is the output of the pg_restore:

It seems that dependencies between extensions are not considered by pg_dump.
