[BUG] JSQLParser Version 4.6 : PostgreSQL : Encountered unexpected token: "," "," when parse upsert sql #1749

Always check against the Latest SNAPSHOT of JSQLParser and the Syntax Diagram

Failing SQL Feature:

I use the plain PostgreSQL upsert syntax.

SQL Example:

• Simplified Query Example, focusing on the failing feature

  INSERT INTO re_rule_mapping ( id, created_time, last_modified_time, rule_item_id, department_id, scene, operation )
              VALUES
                  ( '1', now( ), now( ), '1', '11', 'test', 'stop7' ),
                  ( '2', now( ), now( ), '2', '22', 'test2', 'stop8' ) ON CONFLICT ( rule_item_id, department_id, scene ) 
              DO UPDATE
              SET operation = excluded.operation

but change to the following sql works perfectly:

INSERT INTO re_rule_mapping ( id, created_time, last_modified_time, rule_item_id, department_id, scene, operation )
                VALUES
                    ( '1', now( ), now( ), '1', '11', 'test', 'stop7' ),
                    ( '2', now( ), now( ), '2', '22', 'test2', 'stop8' ) ON CONFLICT ON CONSTRAINT uk_re_rule_mapping
                DO UPDATE
                SET operation = excluded.operation

Note: [rule_item_id, department_id, scene] is a unique constraint named 'uk_re_rule_mapping' in my db table

Software Information:

• JSqlParser version 4.6
• Database (PostgreSQL15)

Tips:

Errors:

net.sf.jsqlparser.JSQLParserException: net.sf.jsqlparser.parser.ParseException: Encountered unexpected token: "," ","
    at line 4, column 88.

Was expecting:

    ")"
