>In order to make it work both things are needed, setting the console mode and a terminal that supports it.
Your patch worked fine on windows which supports VT100. But the bug still happened when set PG_COLOR="always" at Windows Terminal that not support VT100. Please see the attached file “Test_result.png” for the NG result. (I used win7 for this test)
To fix the above bug, I made some change to your patch. The new one works fine on my win7(VT100 not support) and win10(VT100 support).
My understanding of the "always" logic is that it has to be enabled no matter what, even if not supported in current output.
Also, in this new patch(v1), I added some doc change for Windows not support Colorization. Please find the attached patch for so.
You cannot change the release notes, if anything it will be added to 12.2 patch notes. It should be added to the 21 (!) utilities that specify the PG_COLOR usage, but I am not so sure that adding a note stating this feature requires Windows 10 >= 1511 update is really a Postgres business.
Please find attached a version that supports older Mingw versions and SDKs.
