May wish to say ... for simple SELECT queries ... Several left outer joins, subselects and a large number of joins are regularly performed faster in PostgreSQL due to a more mature optimizer. But MySQL can pump out SELECT * FROM table WHERE key = value; queries in a hurry. I've often wondered if they win on those because they have a lighter weight parser / optimizer with less "lets try simplifying this query" steps or if the MYISAM storage mechanism is simply quicker at pulling data off the disk.
