MySQL vs PostgreSQL vs EnterpriseDB

in this test I used:
php 4.x
mysql 5.0.18
postgreSQL 8.0.3
EnterpriseDB 8.1.3.12
Results:

Using unixODBC + EnterpriseDB odbc drivers

As you can see, MySQL is aprox 5 timer faster than Pgsql, EnterpriseDB is tested
using unixODBC drivers, so that migh slow proces a little bit.
