PGSQLStatementParser不支持匿名代码块的解析，丢进去报错了。

执行如下代码

String sql = "DO $do$ BEGIN IF NOT EXISTS (SELECT 1 FROM information_schema.tables WHERE table_name = 't_myoperation') THEN\n"
          + "CREATE TABLE T_MYOPERATION (id BIGINT NOT NULL, creatorid BIGINT NOT NULL DEFAULT 0, orgid BIGINT NOT NULL DEFAULT 0, menuid CHARACTER VARYING (36) DEFAULT ' ', createtime TIMESTAMP WITHOUT TIME ZONE, bizid CHARACTER VARYING (36));\n"
          + "END IF; END $do$;";
      List<SQLStatement> sqlStatements = SQLUtils.parseStatements(sql, JdbcUtils.POSTGRESQL);
      String result= SQLUtils.toSQLString(sqlStatements, JdbcUtils.POSTGRESQL);
      System.out.println(result);

报错

PGSQLStatementParser 能否提供下更多的支持，或者讨论下是否可以给你们提个pr也可以。
