#jVdZddlmZddlmZddlmZegdfZdZddddd Z dS)uDialect dispatcher for Alembic migrations. Each migration file declares a ``_pg_upgrade``/``_oracle_upgrade`` (and matching downgrades) function and routes ``upgrade()``/``downgrade()`` through ``run_for_dialect``. The helper inspects the live connection's dialect name and runs the matching function — or no-ops if the migration doesn't apply to the current backend. Use ``None`` (or omit the kwarg) when a migration intentionally has no effect on a dialect; the helper treats it as a no-op. ) annotations)Callable)opN postgresqloracle)pgrr DialectFn | NonerreturnNonectjjj}|tvrt d|dtd||d|}| |dSdS)aZDispatch to the function matching the current bind's dialect.
