Note that this currently requires superuser privileges.
Given the usefulness of this specific query and that it could be used
without risk of the user being able to gain superuser access through it,
I'd like to see a new function added which does not have the superuser
check, but is not allowed to be called by public initially either.
Something along the lines of 'pg_xlog_file_list()', perhaps. There is a
check in check_postgres.pl which could take advantage of this also.
Should be a very straight-forward function to write, perhaps good as a
starter project for someone.
Thanks!
Stephen
