I concur that returning false is problematic.
For assertion builds, Assert typically provides more detailed
information than elog. However, in this case, it wouldn't matter much
since the worker would repeatedly restart even after a server-restart
for the same reason unless cosmic rays are involved. Moreover, the
situation doesn't justify server-restaring, as it would unnecessarily
involve other backends.
In my opinion, it is fine to replace the Assert with an ERROR.
