When -C/--connect option is specified, pgbench establishes and closes the connection for each transaction. In this case pgbench needs to measure the times taken for all those connections and disconnections, to include the average connection time in the benchmark result. But previously pgbench could not measure those disconnection delays. To fix the bug, this commit makes pgbench measure the disconnection delays whenever the connection is closed at the end of transaction, if -C/--connect option is specified. Back-patch to v14. Per discussion, we concluded not to back-patch to v13 or before because changing that behavior in stable branches would surprise users rather than providing benefits.
