dot-conf checking

Folks,

Here's some things I'd like to check on before submitting a bug patch on the 
.conf stuff:

1) TimeZone and DateStyle are mixed case in SHOW ALL.  Is there a reason for 
this?   Appears to be the same in 7.4.

2) for unix_socket_permissions  the value in the .conf file is octal (0777), 
while SHOW is decimal (511).

3) The .conf file says that rendezvous_name "defaults to host name".  However, 
it appears to default to UNSET.  Is the .conf file wrong, or initdb?

4) Am I correct that these are the only values set at initdb/compile time?wal_sync_methodtimezoneclient_encodinglc_*

Thanks for feedback!
