Hi Mark,
shoveler has been failing for a while with an odd error. E.g.
https://buildfarm.postgresql.org/cgi-bin/show_log.pl?nm=shoveler&dt=2020-09-18%2014%3A01%3A48
Illegal instruction
pg_dumpall: error: pg_dump failed on database "template1", exiting
waiting for server to shut down.... done
None of the changes in that time frame look like they're likely causing
illegal instructions to be emitted that weren't before. So I am
wondering if anything changed on that machine around 2020-09-18
14:01:48 ?
Greetings,
Andres Freund
