FWIW, I'd be rather in favor of doing (3) because this remains simple just to take care of an edge case, even if that partially breaks the promise to rely on a default connection. (4) would be to revisit the decision to make libpq report all the errors stored in its stack with multiple attempts. That would bring back the buildfarm to green at least, and we still need to take a decision about that for 14 anyway as it involves a compatibility breakage. But I agree that we also should do something for 12~ for those tests. > (BTW, I just noticed that regress.c is unsetenv'ing the > SSL connection environment variables, but not the GSS ones. > Seens like that needs work similar to 8279f68a1.) Yes, I saw that I was able to break things is many fancy ways when working on 8279f68a1, but the list of parameters to reset needs to diverge a bit compared to the TAP tests. -- Michael
