If you mean you e.g. only have access to psql on the server in question,
but want to know more about the server itself (i.e. not the PostgreSQL
settings), then you might have luck poking around with the pg_read_file()
function, e.g.:
SELECT pg_read_file('/proc/meminfo');
Note you will need database superuser permission to execute pg_read_file(),
or for non-superusers be granted EXECUTE permission on it.
