Tom Lane e0db288abf Fix libpq's implementation of per-host connection timeouts. ... Commit 5f374fe7a attempted to turn the connect_timeout from an overall maximum time limit into a per-host limit, but it didn't do a great job of that. The timer would only get restarted if we actually detected timeout within connectDBComplete(), not if we changed our attention to a new host for some other reason. In that case the old timeout continued to run, possibly causing a premature timeout failure for the new host. Fix that, and also tweak the logic so that if we do get a timeout, we advance to the next available IP address, not to the next host name. There doesn't seem to be a good reason to assume that all the IP addresses supplied for a given host name will necessarily fail the same way as the current one. Moreover, this conforms better to the admittedly-vague documentation statement that the timeout is "per connection attempt". I changed that to "per host name or IP address" to be clearer. (Note that reconnections to the same server, such as for switching protocol version or SSL status, don't get their own separate timeout; that was true before and remains so.) Also clarify documentation about the interpretation of connect_timeout values less than 2. This seems like a bug, so back-patch to v10 where this logic came in.
