@FranckPachot @philippemnoel Stability is foremost for a database. Everything else is secondary.

@philippemnoel 💯 A popular open source DB used in critical applications without support must be conservative, as "Best is the enemy of the good." Its first value is conservatism. Its second is extensibility, so extensions and forks can build faster on some parts.

The irony here is that Postgres became so ubiquitous precisely because Postgres is so careful with changes
George Fraser@frasergeorgew
Postgres has a lot of problems and the root cause of all of them is an insular core team that rejects improvements. The most egregious example is the copy on write storage engine which was already outdated when it was first implemented in the 1990s. Another insane design choice that has somehow never been revisited is one process per session. PG has become systemically important because for various reasons it has become the default choice for new systems. It would be a good thing for the world if AWS MS and Google would fork it and fix the fundamental problems. Maybe the name Ingres is available?

While stating that most IT professionals read CPU metrics wrong is a bold claim, it is not an exaggeration.
