I'm currently running SQL Server and Postgres in the same project, and I would love to dump SQL Server. Its geospatial "capabilities" are so laughably bad, they should just stop advertising that they exist at all, and the unpredictable locking behavior alone should disqualify it from being used in any modern software project. And sure, it has column stores, which postgres has in extensions, but even if I needed column stores, SQL Server would still be last on my list, because there are so many better options out there.
