It is read from up to down until specific criteria is true. It stops there and doesn't read thru rest of the lines.

Good morning pinker,


Thank you for approch, but i maked this teste:
  1.  Reject xpto  connection from all adress and  after acept  xpto connection from this adress - result  = work good (lock connection for xtpo come from other adress and acept from this adress)

# TYPE  DATABASE        USER         ADDRESS           METHOD
host       xpto                   system       10.72.18.0/24         reject
   host        xpto                   system       0.0.0.0/0                 reject 
   host       xpto                   system       10.75.15.60/32       md5
              host       all                       all             0.0.0.0/0               md5  
 
 
  1.  acept xpto  connection from especific adress and  after reject from all connection - result = (acept all connection, that  come from all adress )

    # TYPE  DATABASE        USER         ADDRESS           METHOD
    host       xpto                   system       10.75.15.60/32       md5
                   host       all                       all             0.0.0.0/0                md5 
                   host       xpto                   system       10.72.18.0/24         reject
                   host        xpto                   system       0.0.0.0/0                 reject 


    So, maybe the read come from up to down? or have other explanation? i don't know, i use postgres 9.4.

    be careful with order change. This proposed by Scott was correct; yours will
    reject all the connections made by user system to xpto. Documentation says:
