This breaks other things, and there are also failing tests.

So the fix needs to be done in the escape serializer and there add quotes if there are any uppercase characters. I actually thought that's how I had done it, but I see I'm missing a test case for it, so gotta look closer if it's a regression or if I simply remember wrong.

A fix would be to add || str !== str.toLowerCase() at the end of line 70 in the escape function

Also add a test like

t('dynamic insert quoting', async() => {
  await sql`create table test ("lowAndUpper" int)`
  const x = { lowAndUpper: 42 }

  return [42, (await sql`insert into test ${ sql(x) } returning *`)[0].lowAndUpper, await sql`drop table test`]
})

Then you can do npm run test afterwards to make sure everything's good ;)

Can you give me a copy of your postgres configs (redacted where necessary) to aid me in setting up the proper ssl environment for your tests, plus any other relevant info I might need?

Oh I'm sorry, I completely forgot there were environment specific things missing to run the tests 🤦‍♂️

I'll get it added to the README.md while I'm at it.

I'd want to set up github actions to run at some point too..
