This fails in the CF bot on Linux because of pg_logging_init() returning with errno=ENOTTY in the TAP tests, for which I began a new thread: https://www.postgresql.org/message-id/[email protected] Not sure if this will lead anywhere, but we can also address the failure by enforcing errno=0 for the new calls of strtol() introduced in this patch. So here is an updated patch doing so. -- Michael
