The 2 problems are:
1. First is that if user changes the config parameter (for ex.
shared_buffers) both by manually
editing postgresql.conf and by using Alter System command and then
reload the config,
it will show the message for parameter 'shared_buffers' twice, but
will only show the last file
where it exists. The detailed description of problem is in current mail.
2. The other problem is in some cases the name of file it display is
junk, problem and fix can be found
