Building tools is one thing, building a system like Postgres or Databases is going to be another thing.
Anyone really tried building PG or MySQL or such a complex system which heavily relies on IO operations and multi threading capabilities
Interesting! I guess that's from your standard benchmark setup. Please note that Fil-C makes no secret of having a performance penalty. It's definitely a pre-1.0 toolchain and only recently starting to pick up some momentum. The author is eager to keep improving it, and seems to think that there's still plenty of low hanging and medium hanging fruit to pick.
It does (or did, at some point) pass the thorough SQLite test suite, so at least it's probably correct! The famous SQLite test coverage and general proven quality might make SQLite itself less interesting to harden, but in order to run less comprehensively verified software that links with SQLite, we have to build SQLite with Fil-C too.
Look at how fanatic the compatibility actually is. Building Postgres or MySQL is conceivable but probably will require some changes. (SQLite compiles and runs with zero changes right now.)
