The CREATE TABLE statements have indeed the same query ID (in 16~),
and the inserts have a different one as they touch different schemas
and relations.  That's quite an old problem, that depends on the
RangeVar attached to an InsertStmt.  I don't quite see a way to
directly handle that except by using a custom implementation in query
jumbling for this node and its RangeVar, so there is no "easy" way to
tackle that :/
