b430701823 When a table is renamed using "ALTER TABLE RENAME TO", update any REFERENCES 
clauses that refer to the table, unless "PRAGMA legacy_alter_table" is true
and "PRAGMA foreign_keys" is set to false (i.e. so that when "PRAGMA
legacy_alter_table" is set behaviour is still compatible with versions 3.24
and earlier).

shadow tables, but is currently an unused placeholder.
