Build a 1000000-vector of pointers to "Keep at it until you get it" and "Great, now move on to tricks" and index into it with [n].

This was pretty eye-opening to me. I had no idea you could use multiplication with booleans like this. Thanks for the lesson!

TRIM(to_char(cast(hits as float) / cast(at_bats as float), '0.999')) as batting_average

^^^^^^
This worked for me, although it looks sloppy

Cute.

Inserting at 0 is not very efficient as it copies the whole string every time. It is better to simply push (to a Vec for example) and reverse everything at the end.

I like cider. :)

You should have replaced $emp_stamp$ with something that's not straight out of PostgreSQL documentation.

Format strings with free "bonus" whitespace—that's one of the more ridiculous language "features" I've seen in a while! 😆

This is whitespace. If you wrap your expression in length(), it will show 6 symbols

same issue, even though iam outputting with to_char

Other answers used tuples (your_type, opponent_type) as keys to the dict instead of plain strings.
