Returns the names of tables that can be reflected, used by `Engine$reflect_schema()`. The default implementation falls back to `DBI::dbListTables()` and ignores `.schema`; dialects with first-class schema support (e.g. PostgreSQL) provide a schema-scoped implementation.
Usage
reflect_tables.postgres(x, .schema = NULL, ...)
reflect_tables(x, .schema = NULL, ...)
reflect_tables.default(x, .schema = NULL, ...)
