Is "Postgres-R 4.1" banned for patent issues?
AP

No, there is no indication that Postgres-R 4.1 has been banned or is unavailable due to patent issues.

Postgres-R 4.1 was released by Crunchy Data in November 2022 and appears to be fully available. Some key points:

    The product download and documentation is freely accessible on the Crunchy Data website.
    There have been no public announcements of any patent disputes or enforced restrictions.
    Postgres-R Community Edition can be downloaded directly without restrictions.
    The Enterprise trial does not indicate any usage limitations or restrictions.
    Crunchy Data blog and Postgres-R release notes make no mention of any patent issues.
    I could not find any public legal notices or filings regarding patents affecting Postgres-R.
    As an open source PostgreSQL extension, it is highly unlikely to have patent constraints.

In general, it would be very rare for an open source technology like Postgres-R to face any patent-related bans. There is no evidence this is the case for the latest 4.1 release. It appears fully available for download and use as advertised by Crunchy Data.
