Paul Guo commented on HAWQ-1378:
--------------------------------
There have been a related pg upstream patch. It looks good. We could basically
follow that.
commit 86947e666d39229558311d7b0be45608fd071ed8

Add more detail to error message for invalid arguments for server
process
It now prints the argument that was at fault.
Also fix a small misbehavior where the error message issued by
getopt() would complain about a program named "--single", because
that's what argv[0] is in the server process.
> Elaborate the "invalid command-line arguments for server process" error.

> Project: Apache HAWQ
> Issue Type: Bug
> Reporter: Paul Guo
> Assignee: Ed Espino
>
> I saw the following errors when running several times,
> "Error dispatching to ***: connection pointer is NULL."
> FATAL: invalid command-line arguments for server process
> While this usually means there is bug in related code but the code should
> have reported more detailed log so that we could catch what argument is wrong
> with less pain, even there is log level switch for argument dumping.
