[英]How to connect PostgreSQL database to Oracle
I have migrated an oracle database to AWS Aurora PostgreSQL.我已将 oracle 数据库迁移到 AWS Aurora PostgreSQL。 My application is connecting to another upstream application on Oracle database on AWS RDS.
我的应用程序正在连接到 AWS RDS 上 Oracle 数据库上的另一个上游应用程序。
I'm generating inventory reports from the upstream application.我正在从上游应用程序生成库存报告。 earlier it was both Oracle databases, so they were using dblink to connect the upstream/downstream databases.
之前都是 Oracle 数据库,所以他们使用 dblink 连接上游/下游数据库。
dblink and postgresql_fdw installed and both are connecting to the different postgres databases not to oracle db.安装了 dblink 和 postgresql_fdw 并且两者都连接到不同的 postgres 数据库而不是 oracle db。
My question is how to I connect to Oracle db from postgres.我的问题是如何从 postgres 连接到 Oracle db。
You cannot.你不能。 You limited yourself by choosing a hosted database.
您通过选择托管数据库来限制自己。
If you had control over the operating system, you could install oracle_fdw, and it would be simple.如果您可以控制操作系统,则可以安装 oracle_fdw,这很简单。
