Re: [WIP] pg_ping utility

Thanks for the updated patches.

Here is the status about the binary patch:
- Code compiles without any warnings
- After testing the patch, it behaves as expected, default option is now verbose, the output can be hidden using -q or --quiet
However, I still have the following comments:
- in pg_isready.c, the function "help" needs to be static.
- the list of options called with getopt_long should be classified in alphabetical order (the option q is not at the correct position)
d:h:p:U:qV => d:h:p:qU:V

Then, about the doc patch:
- docs compile correctly (I did a manual check)
- I am not a native English speaker, but the docs look correct to me. There are enough examples and description is enough. No problems either with the sgml format.

Once the 2 small things I noticed are fixed, this patch can be marked as ready for committer.
Thanks,
