findCompositeByRelation

Returns the row type of the relation with the given relationOid, or null when this dictionary holds none for it.

Unlike the rest of the lookups here, a miss is an ordinary answer rather than a failure: the type load skips composites in pg_catalog and information_schema, and a relation created since the load has no row type here yet. Callers are naming something for a reader, not resolving a type they have to have.
