first, I'd consider this a a sign of robustness.

You've been in software for how long? ... ;)  There's quite mixed
experiences with DMS.

    Actually long enough to understand that if someone "big" calls it production quality, we should not be pickier and assume it is --whether it is or not. People will accept it as such, and that's good enough.

Historically the fact that we have been pickier than many of the "someone big":s is exactly how we ended up with the codebase and relative stability we have today.

Just because someone is big doesn't mean they know what's right. In fact, more often than not the opposite turns out to be true.

    Note that I'm not here supporting test_decoding. I'm just saying is all what is available in-core for 9.4-9.6, and it seems someone with potentially a lot of users tested it and is using it in its own solution. Ask me if I would like an in-core, well tested, performant, with an easy to parse format, and efficient, for 9.4-9.6? My answer would be an immediate 'yes'. But since this is not going to happen, test_decoding is good that is good enough, lucky us, because otherwise there would not be a good solution on this front.
