get_info_from_conninfo returns "host=" in host variable

[nward]

Hi,

I am testing pgpool 4.0.2 at the moment, and note that verify_backend_node_status returns incorrect results, and decides that the replica servers are not connected:

verify_backend_node_status: primary 1 does not connect to standby 0

However, the servers are.

I have inspected the code, and I see that get_info_from_conninfo skips over "port=" but does not skip over "host=", so, the value of host is "host=", while port is simply the string of the port number.

When the comparison between the configured backend_host and host happens, this does not match - of course.

I note that get_info_from_conninfo is not used anywhere else, so I will submit at PR to resolve this by skipping over "host=".

Yes. You are correct.
"host=" should be skipped like "port=".
I will commit your patch.
