Are your results based on a single client accessing the database and no
concurrent updates?

Would adding more clients, and maybe having some client that
updates/inserts into the tables, still make mssql faster then pg? Maybe
it's so simple as pg being optimized for more concurrent users then mssql?

I'm just asking, I don't know much about the inner workings of
mssql.
