I have a use-case for this feature, at part of it containerized 
PostgreSQL. Right now, there is certain diagnostic information (like 
timeline) which is exposed ONLY in pg_controldata.  That leaves no 
reasonable way to expose this information in an API.

(and yes, we have a bigger issue with stuff which is only in pg_log, but 
one thing at a time)
