This can be done but for this we need to change internal functions
internal_load_library
initialize_SSL
postmastermain
The same information needs to be provided for some other parameters also
like 'listen_address', etc.
which are not validated during the configuration parameter set.
How about giving some Warning/Notice message for all postmaster specific
configuration parameters during set persistent as if any problem occurs
during restart please verify the postgresql.auto.conf file?
Also Provide information in User manual as how to recover from such problems
occurs because of postgresql.auto.conf?
