Postgres has Oracle layer, available as a commercial variant by EnterpriseDB. I don't think MariaDB implementation can compete, but EDB Postgres is solid. Basically a native implementation of Oracle in Postgres.

The Oracle layer was also added to IBM DB2.

Which one? Good question. The mainframe, as/400, and Windows versions are all on separate source code last I heard.

DB2 LUW (Linux/Unix/Windows), DB2 iSeries, and DB2 z/OS are three different databases. With the same name - I guess for branding.

Does it replicate the same kind of "evil" bugs as in the article, or does it provide an improvement?

AFAIK it works exactly as Oracle. Doing something barely similar would probably introduce some very expensive bugs in production.
