Please look at a new anomaly introduced with 374c7a229.
Starting from that commit, the following erroneous query:
CREATE FOREIGN TABLE fp PARTITION OF pg_am DEFAULT SERVER x;
triggers an assertion failure:
TRAP: failed Assert("relation->rd_rel->relam == InvalidOid"), File:
"relcache.c", Line: 1219, PID: 3706301

On 374c7a229~1 it fails with
ERROR: "pg_am" is not partitioned
