例如,在 PostgreSQL 中,你可以使用 SET SESSION CHARACTERISTICS AS TRANSACTION READ WRITE; 来将当前会话的事务设置为读写模式。 重新执行操作: 在修改事务设置后,重新执行你的 CREATE TABLE 操作。 检查数据库配置: 如果问题仍然存在,检查数据库的全局配置,确保没有将数据库或特定用户设置为只读模式。 联系数据库...
user:普通用户使用set设置,这类参数修改后和superuser类参数一样,也是只影响自身session。仅当没有通过set 设置会话本地值时,postgresql.conf中的改变才会影响现有的会话

让数据库变成只读模式,目前PostgreSQL没有严格意义上的只读模式(如临时表在只读事务中还是可以使用的)。通过调整参数或设置事务模式可以将后续登录的SESSION或者当前事务设置为只读模式。 在只读模式下,PostgreSQL不允许如下SQL: When a transaction is read-only, the following SQL commands are disallowed:INSERT,UPDATE...
