The question at the end wasn't there, when I wrote comment. The default postgresql config is rather conservative. It is more an open source Oracle with many of its (former) unique features. PL/pgSQL resembles Oracle's PL/SQL procedural language. [1] Most people simply don't understand MySQL. MySQL is unique in as it support many database engines [4], it's like a common SQL layer on top of dozens of database engines. MySQL had a bad reputation because of its old MyISAM engine [2], the former default engine (one of many). The current default database engine is InnoDB [3] which is very fast and is what Facebook and many other huge web sites use. Instead of repeating myself and others, MySQL+memcached is quite popular, check out the highscalability website [5].
