使用Navicat Premium 15访问PostgreSQL 16版本的库,报如下错误

ERROR:  column "datlastsysoid" does not exist
LINE 1: SELECT DISTINCT datlastsysoid FROM pg_database;

登录pg库查看

postgres=# SELECT DISTINCT datlastsysoid FROM pg_database;

Tablespace: "pg_global"

确认没有了datlastsysoid列,通过查看文档确认从Postgres 15版本开始 pg_database表中删除了 datlastsysoid,但是可以通过查询dattablespace替代,使用二进制工具修改libcc.dll文件中的SELECT DISTINCT datlastsysoid部分语句为:SELECT DISTINCT dattablespace

然后重新启动Navicat，访问pg库正常

当然这个问题如果使用高版本的Navicat或者访问低版本的PostgreSQL库不会出现
