That seems reasonable. (Just to check off the obvious, you did
restart the postmaster service afterwards, right?)

There are few if any modern platforms on which the name of a core
file is just "core" -- most people add a PID, for instance.
Searching the whole filesystem is also unlikely to be productive.
I'd just take a look into the PG data directory and see if you
see anything including "core" in its name.
Also, I don't know much about Ubuntu, but if it uses systemd then
probably systemd has commandeered collection of core files and
you need to negotiate with systemd-coredump. (Your reference to
an init.d file makes this theory unlikely, but I mention it
for completeness.)
