我有一个安装了 unixODBC 2.3.1 和 postgresql-odbc 12.02 的 Centos 7 机器，它正在连接到同样运行 v12 的 PostgreSQL 服务器。
虽然我相信我已经将 ODBC 配置为使用 v12.0 协议，但似乎并非如此。当连接到服务器并尝试获取表中的列列表时，我收到错误，column c.relhasoids does not exist。此列已从 PostgreSQL v12 中删除pg_catalog.pg_class。
postgresql-odbc 已特别更新至不使用此列当协议是 v12 时，我只能假设我不是。
我已经Protocol = 12.0在我的/etc/odbcinst.ini，如果我运行，我可以看到它按照配置strace isql my-connector加载 postgresql12 库。/usr/pgsql-12
我困惑了！
