Обсуждение: PG_DUMPALL not executable within docker container
Steps to reproduce:
Startup Container:
```sh
synesc@dockerhost01:$ docker run --rm -it postgres:15.4 /bin/bash
```
Execute PG_DUMPALL, Params not required to see the issue.
```sh
root@13fba0e113c7:/# pg_dumpall
popen failure: Cannot allocate memory
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"
root@13fba0e113c7:/#
```
Was not able to fix the problem, with full parameter list.

pg_dumpall runs the pg_dump binary, so when starting up it locates and tries to
execute pg_dump to check its version. The above error indicates that the
binary does indeed exist, but when trying to execute it there is a problem with
the popen() call. A quick search reveals that this has been reported against
Docker (and has been fixed it seems):
https://github.com/docker-library/postgres/issues/1103
As this is not a bug in postgres, pgsql-general is probably a better
mailinglist to use for help.

Thank you very much. Found the Key point here:

On this different (newer) setup the issues do not exist.
Solution
Use appropriate docker-image.

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.
