Nobody ever said it /can't/ be done. I would never have argued against using a real RDBMS. But I've often been guilty of telling folks that SQLite was "good enough".

Installing PostgreSQL as you described is not "good enough". If you're going to bother with that, you need to understand the database enough to tune it properly, setup backups, test restores, etc. There are more considerations than simply installing it from apt-get and then forgetting about it.

Yes that's true, but by default they come with good configurations which should enable better write and read in most cases against SQLite :)
