Re: signal 11 segfaults with parallel workers

I'm using the Ubuntu PostgresSQL 9.6.3 from this repo:
deb http://apt.postgresql.org/pub/repos/apt/ xenial-pgdg main

It looks like there is a "-dbg" package available:
postgresql-9.6-dbg - debug symbols for postgresql-9.6

I'll give that a try when I get the restart opportunity.
