Database Security

  Hello world ,
  I want to allow all users to access to all databases .  I search the
'pg_ident.conf' that no longer exists , so I tried to use 'pd_hba.conf'.

  The only active record is :
       "local    all           trust"    (with new line character)
   I can connect a local  user to another database , but when I try the
 query :   " select * from pipo ; "  ,  I have this :
    "ERROR:  pipo: Permission denied."

  Any ideas ?
