If you'd just showed this one, my thoughts might bend towards a bug in our sort abbreviation logic, which is relatively new ... > (gdb) bt > #0 0x00007f6e1f09d8ea in get_next_seq () from /lib64/libc.so.6 > #1 0x00007f6e1f09eacc in strcoll_l () from /lib64/libc.so.6 > #2 0x00000000007cf70b in varstr_cmp () > #3 0x000000000075f25b in compareJsonbContainers () > #4 0x000000000075d8f2 in jsonb_eq () ... but this stack trace is not going anywhere near that code.
