Well, now that we have clear warnings when it is misconfigured,
especially when querying the pg_stat_statements view, are these
complaints still valid? Also, how is modifying
shared_preload_libraries zero-config, but modifying
shared_preload_libraries and compute_query_id a huge burden?
I am personally not comfortable committing a patch to add an auto option
the way it is implemented, so another committer will need to take
ownership of this, or the entire feature can be removed.
