To be honest with you, if you have to ask that question, you don't need SQL Server

What a patronizing, obnoxious response. You attempt to follow it up with a justification, but it does the opposite -- remove the first two obnoxious sentences from your reply and it's more coherent and useful, if a little fictitious (1/10th? Really? There is an absolutely enormous amount of tooling for pgsql, including tooling that dramatically changes the underlying product. This doesn't exist for mssql).

I like MSSQL. It's a fast, well tuned product. It's a very good option if you're in the Microsoft camp.

So no, SQL Server is not expensive at all.

More fiction. Aside from Oracle-like per core pricing, in various SQL Server engagements we spent literally hundreds of hours dealing with licensing and compliant bullshit involved with using a commercially licensed product. It is such an engineering relief using Linux+pgsql where those concerns simply disappear.
