fmguerreiro opened a new pull request, #2313:
URL: https://github.com/apache/datafusion-sqlparser-rs/pull/2313
## Summary
- **CREATE STATISTICS** (pgmold-103): parses `CREATE STATISTICS [IF NOT
EXISTS] name [(ndistinct, dependencies, mcv)] ON expr, ... FROM table`. Kinds
are optional; expression list accepts any expression, though in practice bare
column references are the common case.
- **CREATE ACCESS METHOD** (pgmold-104): parses `CREATE ACCESS METHOD name
TYPE INDEX | TABLE HANDLER handler_function`.
- **CREATE EVENT TRIGGER** (pgmold-105): parses `CREATE EVENT TRIGGER name
ON event [WHEN TAG IN ('tag', ...)] EXECUTE FUNCTION | PROCEDURE name()`.
Supports all four event names (`ddl_command_start`, `ddl_command_end`,
`table_rewrite`, `sql_drop`) and the `PROCEDURE` alias.
- **CREATE TRANSFORM** (pgmold-106): parses `CREATE [OR REPLACE] TRANSFORM
FOR type LANGUAGE lang (FROM SQL WITH FUNCTION f(...), TO SQL WITH FUNCTION
f(...))`. `OR REPLACE` is supported; both FROM and TO elements are optional in
the grammar.
## New keyword
`TRANSFORM` added to `keywords.rs` alphabetically.
## Notes
- Fork CI does not auto-run on this branch.
- `verified_stmt` round-trip tests included for each variant (2–3 per
statement).
