在我的pg_hba.conf文件中,我有：

# TYPE  DATABASE        USER            ADDRESS                 METHOD
# "local" is for Unix domain socket connections only
local   all             all                                     trust
# IPv4 local connections:
host    all             all             127.0.0.1/32            trust
# IPv6 local connections:
host    all             all             ::1/128                 trust
# Allow replication connections from localhost,by a user with the
# replication privilege.
#local   replication     Andrew                                trust
#host    replication     Andrew        127.0.0.1/32            trust
#host    replication     Andrew        ::1/128                 trust

local all all md5

也许我做错了？

谢谢
