Description
Dialect
MySQL, PostgreSQL
Failing SQL
DELETE FROM t USING a WHERE a.id = t.id;
Description
Unfortunately, this is not a valid ANSI SQL statement, but many vendors accept this:
MySQL: https://dev.mysql.com/doc/refman/5.7/en/delete.html
PostgreSQL: https://www.postgresql.org/docs/current/sql-delete.html

Research direction
Start with the SQL parsing support for DELETE statements and compare the requested syntax with the MySQL and PostgreSQL documentation linked in the issue. No source file or test is named, so locate the relevant parser tests before implementing support for DELETE FROM t USING a WHERE a.id = t.id; done means this statement parses for the stated dialects.
