It turns out that this breaks my local build, too, so I went ahead and
pushed a fix.
At least two buildfarm members think there's something deeper broken
here:
2017-09-15 00:08:34.061 EDT [97092:75] LOG: worker process: parallel worker for PID 101175 (PID 101256) was terminated by signal 11: Segmentation fault
2017-09-15 00:08:34.061 EDT [97092:76] DETAIL: Failed process was running: select * from pg_get_object_address('operator of access method', '{btree,integer_ops,1}', '{int4,bool}');
I wonder if this indicates you forgot to consider transmission of state
to parallel worker processes.
regards, tom lane
