Translation isn't an issue here because the first group of messages
are reported using elog(), not ereport(). There is something to be
said for being consistent, though.

I feel like it's kind of awkward that this thing is named Zstandard
but the library is libzstd and the package name is probably also zstd.
I worry a bit that if we make the messages say zstandard instead of
zstd it makes it harder to figure out. It's probably not a huge issue,
though.
