org.hibernate.exception.SQLGrammarException: could not extract ResultSet in heroku
问题
Good day.
我有一个部署在Heroku上的应用程序。应用程序使用Spring Boot编写。在本地运行正常，如果我在Heroku中输入（admin，插入到liquebase的密码），则在Heroku中正常工作。我可以打开带有迁移数据的页面。但是，如果我想创建新用户或新主题（如插入到DB中），我会收到org.hibernate.exception.SQLGrammarException：无法提取ResultSet错误。我完全不知道如何修复它。你能帮助我吗？
我使用的是PostrgeSQL，Spring Boot。
liquibase脚本：
schema.sql

The reasone in scripts of schema.sql and insert.
For Heroku you should use id auto creation SERIAL.
For Models ID generation strategy @GeneratedValue(strategy = GenerationType.IDENTITY)
Samples below
schema.sql
CREATE TABLE usr
(
id SERIAL primary key,
active boolean NOT NULL,
email character varying(255),
first_name character varying(255),
last_name character varying(255),
password character varying(255),
username character varying(255)
);
CREATE TABLE user_role
(
user_id SERIAL,
roles character varying(255),
CONSTRAINT fk_user_role_us FOREIGN KEY (user_id)
REFERENCES usr (id) MATCH SIMPLE
ON UPDATE NO ACTION ON DELETE NO ACTION
);
CREATE TABLE topic
(
id SERIAL primary key,
content character varying(255),
created timestamp without time zone,
name character varying(255),
user_id bigint,
CONSTRAINT fk_topic FOREIGN KEY (user_id)
REFERENCES usr (id) MATCH SIMPLE
ON UPDATE NO ACTION ON DELETE NO ACTION
);
CREATE TABLE comments
(
id SERIAL primary key,
text character varying(255),
user_id bigint,
topic_id bigint,
CONSTRAINT fk_comments_us FOREIGN KEY (user_id)
REFERENCES usr (id) MATCH SIMPLE
ON UPDATE NO ACTION ON DELETE NO ACTION,
CONSTRAINT fk_comments_to FOREIGN KEY (topic_id)
REFERENCES topic (id) MATCH SIMPLE
ON UPDATE NO ACTION ON DELETE NO ACTION
);
insert.sql
insert into usr (active, email, first_name, last_name, password, username) values (TRUE,'mrArxi@gmail.com','Vladimir','Vladimir','12345','Rustymattok');
insert into user_role(user_id,roles) values((select id from usr where username = 'Rustymattok'), 'ADMIN');
insert into topic(content,created,name,user_id) values ('smth','2016-06-22 19:10:25-07','Vladimir test',(select id from usr where username = 'Rustymattok'));
insert into comments(text,user_id,topic_id) values ('spring boot help',(select id from usr where username = 'Rustymattok'),(select id from topic where name = 'Vladimir test'));
sample of Model
@Entity
@Table(name = "usr")
public class User implements UserDetails {
@Id
@GeneratedValue(strategy = GenerationType.IDENTITY)
private Long id;
