We have a DB2 database and a Postgres database sitting side-by-side on our iSeries/as400. Is there a way to access the Postgres data from DB2 (or vice versa)?
It could be creative solutions rather than just a way to do cross-SQL statements, which I don't know is possible.
The reason we want to start using Postgres is the wealth of Node.js libraries out there that support it (and don't support DB2). For example, Strapi easily builds out a RDBMS in Postgres and automatically generates a GraphQL + REST API.
