数据安全：Postgresql如何设置远程访问的方法，置防火墙或者关闭防火墙

Postgresql我通过百度已经将pg_hba.conf和postgresql.conf文件设置好（网上bd一大堆）

pg_hba.conf

# TYPE DATABASE USER ADDRESS METHOD
host all all 0.0.0.0/0 trust
# IPv4 local connections:
host all all 127.0.0.1/32 md5
host all all 0.0.0.0/0 trust
# IPv6 local connections:
host all all ::1/128 md5
# Allow replication connections from localhost, by a user with the
# replication privilege.
host replication all 127.0.0.1/32 md5
host replication all ::1/128 md5
