- NAM001/2/3 table/column/function names not snake_case (quoted identifiers only)
- `pgtidy lint [--only=ID,...] [files...]`; exits 1 on findings, 2 on error.
- Fixture SQL in `testdata/lint/`; 6 tests covering violations + clean fixtures.
- **Function bodies** (`pkg/lint/plpgsql.go`): `plpgsql` `CREATE FUNCTION/PROCEDURE` and `DO` bodies are parsed with the PL/pgSQL parser. Syntax errors are reported as `PLPGSQL` (located by the offending token, since libpg_query gives no position), and every embedded SQL statement is run through the normal rules with line/col mapped back to the file. Embedded findings carry no autofix. Non-plpgsql languages are skipped.
- `--fix` rewrites files in place applying autofixes; for stdin, prints fixed SQL to stdout.
- Autofixable: **MIG001** (insert `CONCURRENTLY` after `INDEX`) and **MIG003** (insert `NOT VALID` before `;`). MIG002, COR*, NAM* are intentionally not autofixable.
- `pkg/diagnostics.TextFix{Offset, End, New, Title}` — byte-range replacement attached to `Diagnostic.Fix`.
