参数解析listen_address：服务器监听客户端连接的TPC/IP地址port：服务器监听的TPC端口max_connections：允许和数据库连接的最大并发连接数superuser_reserved_connections：为超级用户连接而保留的连接数tcp_keepalives_idle：在一个TCP连接中空闲多长时间后会发送一个keepalive报文（建议值180）tcp_keepalives_interval：在一个空闲TCP连接中，在发送第一个keepalive报文后如果在该参数指定的时间间隔内没有收到对端的响应报文，则开始发送第二个keepalive报文（建议值10）tcp_keepalives_count：在一个空闲TCP连接中，在发送keepalive报文后，如果一直没有收到对端的响应报文，最多发送该参数指定次数报文后，认为TCP连接已中断（建议值3）shared_buffers：数据库实例可使用的共享内存区域temp_buffers：每个数据库会话使用的临时内存区，只用于访问临时表，在服务进程中分配的，属于本地内存work_mem：排序与散列操作在使用临时磁盘文件之前可使用的内存区域，属于本地内存maintenance_work_mem：在维护性操作中可使用的内存区域wal_level：决定有多少信息可写入WAL日志中fsync：决定是否使用fsync系统调用，将文件系统中的脏页写到物理磁盘synchronous_commit：提交一个事务是否需要等待将WAL日志写入磁盘后在返回wal_sync_method：指定向磁盘写WAL日志的方法full_page_writes：数据库实例会在检查点之后对页面第一次修改时将整个页面写入WAL日志wal_buffers：WAL日志使用的内存区域，属于数据库实例共享内存log_destination：stderr,csvlog,sysloglog_directory：日志输出的路径log_filename：日志文件名log_rotation_age：日志超过多长时间，就生成一个新的文件log_rotation_size：日志超过多大，就生成一个新的文件log_truncate_on_rotation：当生成的新文件的文件名已存在，是否覆盖同名旧文件
