No need to prefix each line with the program name; this was pretty
inconsistent anyway. The only place where log output needs to identify
the outputting program is when syslog is being used, which is done
anyway.
Daemonizing changes the current working directory to '/',
which breaks configuration file parsing if the file is in
the previous working directory and provided without an
explicit path.
Also it makes general sense to parse the configuration file
before daemonizing.

On 9.4 we have logical decoding, which introduced a new wal_level called
logical. This level includes all the previous ones, so you can run a
hot_standby if wal_level = logical, because the relevant information for
hot_standby will be there, plus other information needed for logical
decoding.
We fix this be adding a second check when wal_level is not hot_standby.
This makes keeping track of events such as failovers
much easier. Note that this is for convenience and is
not a foolproof auditing log.
