Since edge Private — implementation detail, not part of the public APISignature
resolved_tables(schema, tables)An unqualified name resolves to the first schema on the search path that has it, the way ::regclass would for a single table. The readers join what they read against this, so a name is read from the one table it names rather than from every schema on the path that also has it.
