The following bug has been logged on the website:
Bug reference: 18115
Logged by: Vasileios Giannakidis
Email address: vasilgiann@gmail.com
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.

I don't know anything about aws_s3, but the only inter-extension
dependencies that are tracked by PG are those that are declared
in the extension control files (via "requires" entries).
Sounds to me like aws_s3 has failed to declare its dependency
on plpgsql.

This is something specific to RDS per the AWS docs:
https://docs.aws.amazon.com/AmazonRDS/latest/UserGuide/USER_PostgreSQL.S3Import.html
So, yes, that's something to take to them to make sure that the
dependency ordering is correctly tracked, I guess.
