Mongo, on the other hand, has definitely always had the racist/ablist slur as the first connotation for me.
"Almost all" does sound like a bit of a surprise, but thinking back on it the only one I know for a fact I heard for the first time outside of a corrective context was my elder uncles friends who enjoyed self-depreciating jokes, usually with slurs for eastern Europeans in them. I first heard those as a child and only realized years later they were offensive. Most others, I think, I honestly have no idea when i was first exposed to them.

My pet theory is that the database is named after a character in "Blazing Saddles", and I want to be able to store candy in it.
In the UK that would be "mong", for us Mongo is the planet Ming The Merciless is from.
Even Croach would be a massive branding improvement.
This is similar to how gimp is a terrible brand.
