It is often useful to be able to use the `postgres' user for management tasks,
so this commit allows setting that. The default behavior is not changed.
I have also added missing exports and sorted them by alphabet.
* gnu/services/databases.scm (%default-home-directory): New variable.
(<postgresql-configuration>): Add home-directory, allow-login? fields.
(create-postgresql-account): Use them.
* doc/guix.texi (Database Services): Document it.
