URL: https://github.com/apache/datafusion-sqlparser-rs/pull/2626
<!-- comma separated, or `none` -->
Dialects: PostgreSQL
Closes #2624.
PostgreSQL's `INSERT` takes `OVERRIDING { SYSTEM | USER } VALUE` between the
column list and the source:
```sql
INSERT INTO t (id, a) OVERRIDING SYSTEM VALUE VALUES (1, 'x')
INSERT INTO t OVERRIDING USER VALUE SELECT * FROM u
```
- Adds an `OVERRIDING` keyword, an `InsertOverriding { System, User }` enum
and an `Insert::overriding` field. The clause is parsed after the column list
(and the Hive/Databricks clauses that follow it), and printed back in the same
position, so statements round-trip.
- PostgreSQL accepts an `INSERT` table alias without `AS`, so without a
column list `OVERRIDING` was read as the alias. It is now excluded from the
implicit alias, as `BY NAME` already is (`OVERRIDING` followed by `SYSTEM` or
`USER` only).
- Tests in `tests/sqlparser_postgres.rs` cover:
- both kinds, with VALUES and with a query source;
- no column list, with an explicit alias, and followed by `ON CONFLICT …
RETURNING`;
- that a plain `INSERT` has no clause;
- malformed `OVERRIDING` forms are rejected.
