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.
