US police (including border agents) are stealing things from citizens. It doesn’t matter if you have bank statements or receipts if you are dealing with someone who will just steal your shit and claim legal immunity.

We have both MySQL and PostgreSQL in our production environment. Postgres is way nicer as a user of the DB. I created a document months ago outlining a dozen different things that Postgres does that MySQL either doesn’t do or does worse. I can’t speak to managing the DB as I don’t have experience with that.
