What's the basis for this change? The one on line 1253 looks like a mistake, but since the other fields are regex matched if we want to match a literal dot we need to escape it.

By looking at the majority of lines in db_tests I concluded that "Match 1", "Match 1 or", ..., "Fail 2" fields are regex matched strings and I found some tests have dot character not escaped where there should be literal dot.

Thanks I looked closer and fixed my brain, I thought you were removing \. sequences from the regex matches. This is a helpful PR, thank you.
