`pkg --debug upgrade` output

I have locked postgresql94-client to avoid binary pkg upgrades causing postgres
being downgraded to 9.3.

I am now receiving this error when running `pkg upgrade` and it is generating a
17MB core:
Assertion failed: (cun != NULL), function pkg_conflicts_check_chain_conflict,
file pkg_jobs_conflicts.c, line 499.
