Ping() is not overlay/network or kubernetes friendly

[Bonn93]

Whilst developing a go based web app in docker, using the Ping() function to check the connection works in a majority of cases, however.

When Postgres is provided on a network that does not support ICMP, or exposed via a v1/service in kubernetes, ping is not the best test and will fail. Some networks may also drop ICMP traffic causing the use of this function to throw errors.

Is there a better way to perform this that's more friendly to overlay networks or kubernetes services?

Hi,
Wouldn't it be more misleading to have a Ping() function which does not connect through ICMP?
Looking for this I saw ExecSimpleQuery(q string), which combined with a dummy query like SELECT 1; could fit your need
