I agree that I would not normally use Cygwin to run a Postgres instance. 
But its psql is nicer than others on Windows because unlike the native 
builds we build it with readline. That's why I've kept a buildfarm 
animal going all these years. If the maintenance burden were high I 
wouldn't do so - but it's not really. And these patches are tiny.

What I might do with the new animal is run just enough TAP tests to 
exercise psql. That would reduce the errors we get, so it would be less 
bother to anyone.


cheers
