以下使用带有 Spring Boot、Hibernate、JpaRepository、CockroachDB 和 Kotlin 的数据库索引的最小示例无法重新启动。
我还使用 PostgresSQL 而不是 CockroachDB 进行了测试，这很好。
|------------------------------------------|
| | PostgresSQL | CockroachDB |
|-----------+---------------+--------------|
| no index | OK | OK |
| index | OK | ERROR |
|------------------------------------------|
但是对于 CockroachDB，它会以 SQL 语法错误结尾（请参阅本问题末尾的日志）。
这是重现问题的代码。

以下是重现问题的步骤。
下载并初始化 CockroachDB：
# download
wget -qO- https://binaries.cockroachdb.com/cockroach-v1.1.6.linux-amd64.tgz | tar xvz
# start
./cockroach-v1.1.6.linux-amd64/cockroach start --insecure
# leave terminal open in background
# init
./cockroach-v1.1.6.linux-amd64/cockroach sql --insecure -e "CREATE USER root WITH PASSWORD '123';"
./cockroach-v1.1.6.linux-amd64/cockroach sql --insecure -e "CREATE DATABASE things_db;"
./cockroach-v1.1.6.linux-amd64/cockroach sql --insecure -e "GRANT ALL ON DATABASE things_db TO root;"
运行数据服务：
gradle bootRun
# wait until started
# then ctrl+c to stop
现在让我们看一下数据库中生成的表：
./cockroach-v1.1.6.linux-amd64/cockroach sql --insecure -e "SHOW COLUMNS FROM things_db.thing;"
输出：
# Server version: CockroachDB CCL v1.1.6 (linux amd64, built 2018/03/12 17:58:05, go1.8.3) (same version as client)
# Cluster ID: 2f85d639-a096-4ebc-a478-216a4e7e3a14
+-------+-------------+-------+---------+---------------------------+
| Field | Type | Null | Default | Indices |
+-------+-------------+-------+---------+---------------------------+
| id | BIGINT | false | NULL | {"primary","value_index"} |
| value | STRING(255) | true | NULL | {"value_index"} |
+-------+-------------+-------+---------+---------------------------+
(2 rows)
然后
./cockroach-v1.1.6.linux-amd64/cockroach sql --insecure -e "SHOW INDEXES FROM things_db.thing;"
输出
# Server version: CockroachDB CCL v1.1.6 (linux amd64, built 2018/03/12 17:58:05, go1.8.3) (same version as client)
# Cluster ID: 2f85d639-a096-4ebc-a478-216a4e7e3a14
+-------+-------------+--------+-----+--------+-----------+---------+----------+
| Table | Name | Unique | Seq | Column | Direction | Storing | Implicit |
+-------+-------------+--------+-----+--------+-----------+---------+----------+
| thing | primary | true | 1 | id | ASC | false | false |
| thing | value_index | false | 1 | value | ASC | false | false |
| thing | value_index | false | 2 | id | ASC | false | true |
+-------+-------------+--------+-----+--------+-----------+---------+----------+
(3 rows)
然而运行
gradle bootRun
第二次不起作用。应用程序在启动时崩溃。
