	Sure, postgres is (a bit but not much) slower for a simple query like  
SELECT * FROM one table WHERE id=some number, and postgres is a lot slower  
for UPDATES (although I heard that it's faster than MySQL InnoDB)... but  
try a query with a join on few tables, even a simple one, and postgres  
will outperform mysql, sometimes by 2x, sometimes 1000 times. I had a case  
with a join between 4 tables, two of them having 50k records ; I was only  
pulling 6 records... mysql spent half a second and postgres 0.5 ms... hell  
!
