General changes

I have tested the extension after recent changes in Multicorn2 against PostgreSQL 15 and 16, which have not been supported by now.

The installation examples had to be changed due to changes in Python 3.11, see PEP 668.
The problem here is, that Pythons pip3 needs a parameter, –break-system-packages, to install packages globally instead inside a virtual environment and a virtual environment is the last thing you’d like to have while accessing Python scripts from within a database server.

In addition the support of unsupported PostgreSQL versions have been changed. Currently PostgreSQL 12, 13, 14, 15, 16 are suppored.

There have been no changes on source code of sparql_fdw.

Update 2024-07-30

The changes of the documentation have been merged into the original repository https://github.com/jaiminpan/cassandra2_fdw.
