apd_set_session_trace_socket

参数

tcp_server

IP or Unix Domain socket (like a file) of the TCP server.

socket_type

Can be AF_UNIX for file based sockets or APD_AF_INET for standard tcp/ip.

port

You can use any port, but higher numbers are better as most of the lower numbers may be used by other system services.

debug_level

由加上 XXX_TRACE 常量而形成的整数。

不建议使用 MEMORY_TRACE。这会很慢且似乎不精确。 ASSIGNMENT_TRACE 还未被实现。

要打开所有跟踪功能(TIMING, FUNCTIONS, ARGS SUMMARY (比如 strace -c)) 则使用 99 作为值。
