Here are things I've noticed.
1. Is adding guc to postgresql.conf.sample useful for users?
2. When proxy_port is a bit large (perhaps more than 2^15), connection failed
though regular "port" is fine with number more than 2^15.
$ bin/psql -p 32768

psql: error: could not connect to server: invalid port number: "-22768"
3. When porxy_port is 6543 and connection_proxies is 2, running "make installcheck" twice without restarting server
failed.
This is because of remaining backend.

ERROR: database "regression" is being accessed by other users
DETAIL: There is 1 other session using the database.

"postgres"
4. When running "make installcheck-world" with various connection-proxies, it results in a different number of errors.
With connection_proxies = 2, the test never ends. With connection_proxies = 20, 23 tests failed.
More connection_proxies, the number of failed tests decreased.
