It looks like we can leave in most of the test cases for Infinity/NaN inputs, but buildfarm member jacana gets the wrong answer for acosh(Inf). It's not worth carrying a variant expected file for that, so just disable that one test. Discussion: https://postgr.es/m/E1h3nUY-0000sM-Vf@gemulon.postgresql.org
