[BUG] JSQLParser 4.9 fails to parse subsequent statements after parsing FUNCTION statement

[kxed]

hi there！

I am using the JSQLParser4.9 tool to parse SQL DDL statements, but I encountered a problem when parsing the following statement:

SQL Example:

• Simplified Query Example, focusing on the failing feature

  -- Replace with your ACTUAL example
  DROP FUNCTION IF EXISTS "fin"."restore_fund_data"("in_fund_id" int8);
  CREATE OR REPLACE FUNCTION "fin"."restore_fund_data"("in_fund_id" int8)
  RETURNS "pg_catalog"."varchar" AS $BODY$
  DECLARE
    message VARCHAR;
    open rec_cur;
    close proj_info_cur;
    ********
    RETURN 'success';
  END $BODY$
  LANGUAGE plpgsql VOLATILE
  COST 100;

Software Information:

• JSqlParser 4.9 and 4.8
• Database PostgreSQL

Thank you very much!

Greetings.

Both statements get parsed and no error message is thrown.

What exactly is the challenge please?

The "INDEX" keyword also failed to convert.

CREATE INDEX "index_keyword" ON "inter"."inter_ti_rec" USING btree (
  "keyword" COLLATE "pg_catalog"."default" "pg_catalog"."text_ops" ASC NULLS LAST
);

Executing the following code will throw an exception.

try {
            Statements statements = CCJSqlParserUtil.parseStatements(sql);
            return statements;
        } catch (JSQLParserException e) {
            log.error(e.getMessage());
            throw new RuntimeException("Failed to parse the Sql file, please check if the Sql file is correct.");
        }
