Uhm...
I'm not practical with apt repos, but, in the Release file, Buster has:
```
Origin: apt.postgresql.org
Label: PostgreSQL for Debian/Ubuntu repository
Suite: buster-pgdg
Codename: buster-pgdg
Date: Tue, 29 Mar 2022 13:35:36 UTC
Architectures: amd64 arm64 i386 ppc64el
```
whereas Stretch has:
```
Origin: apt.postgresql.org
Label: PostgreSQL for Debian/Ubuntu repository
Suite: stretch-pgdg
Codename: stretch-pgdg
Date: Tue, 29 Mar 2022 13:35:38 UTC
Architectures: amd64 i386 ppc64el
```
Does it mean that there are no arm packages on stretch?
