The original coding in commit1e8a85009didn't use PQconnectPoll per spec, and while the rewrite ine434ad39ais closer, it still doesn't guarantee to wait until the socket is read-ready or write-ready (as appropriate) before calling PQconnectPoll. It's not clear whether that omission is causing the continuing failures on buildfarm member bowerbird; but given the lack of other explanations meeting the available facts, let's tighten that up and see what happens. An independent issue in the same loop was that it had a race condition whereby it could clear the process's latch without having serviced an interrupt request, causing failure to respond to a cancel while waiting for connection (the very problem1e8a85009was meant to fix).
