// Queries to validate referential integrity in the indexed data:
// At the given block number,
// In each table, for each (would be) foreign key reference, perform left join with the referenced table on the foreign key fields.
// Select rows where there are no matching rows in the referenced table.
// If any such rows exist, there are missing entries in the referenced table.
