I added additional comments marked setting which need server restart to
take effect. I use (!RSR!) tag for it, however if anybody have different
idea, let me know and I will change it.
I removed comments about commenting out behavior too, because patch now
waiting for commit (or reject?).

# allowed values can be found in the PostgreSQL documentation. The
# commented-out settings shown in this file represent the default values.

- # Please note that re-commenting a setting is NOT sufficient to revert it
- # to the default value, unless you restart the postmaster.
- #
# Any option can also be given as a command line switch to the
# postmaster, e.g. 'postmaster -c log_connections=on'. Some options
# can be changed at run-time with the 'SET' SQL command.
