The agent patch implements both required behaviors: parsing/AST/display support for `ALTER TABLE ... ADD CONSTRAINT ... NOT VALID` and `ALTER TABLE ... VALIDATE CONSTRAINT ...`, including keyword addition and span handling. It also updates dependent pattern matches/tests for the `AddConstraint` shape change and adds PostgreSQL tests. Differences from gold (field naming and explicit dialect gating to Postgres/Generic) do not change intended functionality.
Code Review
The patch is close and includes the main AST/parser/test additions, but a parser behavior inconsistency around dialect gating versus global expected-token messaging makes it unlikely to be fully correct as submitted.
The patch only parses `VALIDATE CONSTRAINT` (and `NOT VALID` on `ADD CONSTRAINT`) for `PostgreSqlDialect | GenericDialect`, but also updates the generic ALTER TABLE expected-token message to include `VALIDATE CONSTRAINT` unconditionally. This mismatch can cause non-PG dialect behavior/regressions and likely explains test instability.
