Repository: AlecStrong/sql-psi (kotlin)

Issue:
PostgreSQL column-list syntax
Dialect: PostgreSQL

failing sql:

```sql
update:
    UPDATE lastSeen SET (userid, timestamp) = (:userid, :timestamp)
    WHERE lastSeen.account = :account AND lastSeen.username = :username
;
```

example from postgresql docs:

```sql
UPDATE weather SET (temp_lo, temp_hi, prcp) = (temp_lo+1, temp_lo+15, DEFAULT)
  WHERE city = 'San Francisco' AND date = '2003-07-03';
```
