Day job. Never had to pay for it out of my own pocket! I've worked at MS shops for quite some time.

Also while we can do what we like with our newer SaaS offerings, getting some of our on-prem clients to use PG over SQL Server would be an uphill struggle so not considering other options isn't entirely our decision.

That $15K sounds like an Enterprise Edition costing too, IIRC Standard is significantly cheaper. Most don't need Enterprise, especially since 2016Sp1 when a lot of previously Enterprise-only features became available in all editions (including the free Express edition in many cases). Developer edition is currently free (licensed for development use only, of course) and is essentially Enterprise edition with different licensing terms.
