Where T-SQL is not enough, one can use basically any .Net language, but there are some restrictions to it, and I have never used this feature. Embedded R in SQL Server as well. Postgres is my default database choice, or SQLite if it's small, but SQL Server is a solid, high performance product and I'll gladly run it for the most demanding workloads.
