Well as Tom Lane said a database will not have an OID of 0, so we need
to know where that is coming from. On the oft chance it occurred in your
9.6 cluster can you see if:

select oid, datname from pg_database;

in the 9.6 cluster shows an OID of 0.

Also:

1) OS and version you are using?

2) Where are you getting you Postgres from?:
a) Package
Repo?
b) Source
File source?

3) Where there any issues with 9.6 cluster before you tried to upgrade
from it?
