I've managed to get a shorter repro for the issue:

BEGIN;
CREATE TABLE the_log (
ts TIMESTAMPTZ NOT NULL DEFAULT CURRENT_TIMESTAMP,
"user" TEXT NOT NULL DEFAULT current_user,
action TEXT NOT NULL,
table_schema TEXT NOT NULL,
table_name TEXT NOT NULL,
old_row JSONB,
new_row JSONB,
CHECK(
CASE action
WHEN 'INSERT' THEN old_row IS NULL AND new_row IS NOT NULL
WHEN 'UPDATE' THEN old_row IS NOT NULL AND new_row IS NOT NULL
ELSE /*DELETE, and maybe TRUNCATE, if that's supported by access to old rows */
old_row IS NOT NULL AND new_row IS NULL
END
)
) PARTITION BY LIST(table_schema);
CREATE TABLE public_log
PARTITION OF the_log FOR VALUES IN ('public');
INSERT INTO the_log (action, table_schema, table_name, new_row)
VALUES ('INSERT','public','city','{"name": "Oakland", "population": 419267}');

leads to:

ERROR: no partition of relation "the_log" found for row
DETAIL: Failing row contains (2016-12-15 00:59:17.980094-08, shackle, INSERT, public, city, null, {"name": "Oakland", "population": 419267}).

Per Thomas Munro, could it be that the CREATE ... PARTITION OF ... code
fails to run CacheInvalidateRelcache on its parent(s)?

Best,
David.
