Thanks!

I am not sure that deleting all the mentions would be a good idea, as
we'd lose track of which tool supports coloring or not, and that could
confuse users. What about switching the existing paragraph to a
simple sentence with a link to the new appendix you are adding? Say:
"pg_foo supports <place_your_link_here>colorized output</>".

A reference to SGR to understand better what's the list of values
supported would be nice?

Could it be possible to have more details about what those three
fields map to?
