Where you get screwed is when some legacy system of record application requires Oracle. So you think, I'll cheat and use Postgresql with an Oracle dialect. Then you find out the application uses tens of thousands of lines of PL/SQL including some of the most obscure features. Now you're looking at millions of dollars to get off the database software you don't like. Oracle, IBM, etc can buy time like this but eventually all the proponents of their software will be retired and the halls of IT will be filled with an army of "never again."

We meet on Wednesdays; the coffee and cookies are free.
