The workload to generate multixids before upgrade is very slow on buildfarm members running with JIT enabled. The workload runs a lot of small queries, so it's unsurprising that JIT makes it slower. On my laptop it nevertheless runs in under 10 s even with JIT enabled, while some buildfarm members have been hitting the 180 s timeout. That seems extreme, but I suppose it's still expected on very slow and busy buildfarm animals. The timeout applies to the BackgroundPsql sessions as whole rather than the individual queries. Bump up the timeout to avoid the test failures. Add periodic progress reports to the test output so that we get a better picture of just how slow the test is. In the passing, also fix comments about how many multixids and members the workload generates. The comments were written based on 10 parallel connections, but it actually uses 20.
