Re: PG_DUMPALL not executable within docker container

Issue exists with docker image postgres:15.4

PG_DUMPALL 
postgres |   popen failure: Cannot allocate memory 
postgres |   pg_dumpall: error: program "pg_dump" is needed by pg_dumpall but was not found in the same directory as "/usr/lib/postgresql/15/bin/pg_dumpall" 
 
STARTUP/INITDB

postgres | popen failure: Cannot allocate memory
postgres | initdb: error: program "postgres" is needed by initdb but was not found in the same directory as "/usr/lib/postgresql/15/bin/initdb" 

Different Setup: 
master@dockerhost:~/$ lsb_release -a
No LSB modules are available.
Distributor ID:
Ubuntu Description: Ubuntu 22.04.3 LTS
Release: 22.04
Codename: jammy
master@dockerhost:~/$ docker --version
Docker version 24.0.6, build ed223bc

On this different (newer) setup the issues do not exist.

Solution
Use appropriate docker-image.
https://askubuntu.com/questions/445487/what-debian-version-are-the-different-ubuntu-versions-based-on

version | ubuntu | debian
22.04 | jammy | bookworm/ sid
20.04 | focal | bullseye/ sid

With the docker-image postgres:15.4-bullseye it does work on the Ubuntu 20.04 setup.
Not really happy with the behaviour. Would suggest to add a note to docker-hub description what image to pick.
