Hi ,

shudn't  "host" lines in pg_hba.conf be in format
host         database    user    ip mask   method

in lines below u missed the user part:

> host         all         127.0.0.1     255.0.0.0           md5
> host         dbname      0.0.0.0       255.255.255.255     md5

i think pg_hba.conf is pretty cool otherwise.

regds
mallah.
