sparql_fdw Forreign Data Wrapper
The sparql_fdw is a foreign data wrapper to connect to query web databases with the SPARQL protocol from inside PostgreSQL written in Python.
Test Against PostgreSQL 18
As multicorn2 is already working with PostgreSQL 18, I tested the sparql_fdw, too.
It worked like a charm and I have added PostgreSQL 18 to the supported versions in the README file.
In addtion I removed PostgreSQL 12 as supported version as that version is out of support.
