Performance also depends a lot on the driver.
For instance, the PHP driver for MySQL is very very fast. It is also very

Why do you say opposite results ?

postgres - returns results in 2.8 seconds
What kind of plan does it do ? seq scan on the big tables and hash join
on the small tables ?
mysql - takes around 16 seconds (This is with myisam ... with
innodb it takes 220 seconds)
I'm not surprised at all.

There are some pitfalls to pgsql though, especially for existing SQL
code using MAX and some other things which can really be blindsided

A consultant did a project for us and chose MySQL. We thought it was
cool that MySQL was free.
Turns out, MySQL costs over $500 (USD) if you are a commercial
organization like us! Even worse, we have to formally transfer
licenses to customers and any further transfers must include
involvement
So, our problem in installing is we don't know a cluster or SSL from a

talking about a user of the system or the database? Yikes, do I need

No you don't need to write it

Amit,
- We have lot of foreign keys between the tables
Do you need these keys to be enforced? Last I checked, MySQL was still
having trouble with foriegn keys.
- Most of the DB usage is Selects. We would have some inserts but that
would be like a nightly or a monthly process

If you have problems with performance, you might want to look into using JDBC

for sure that they dont support bizgres. Now the question is what
difference is there between bizgres and postgres ... I guess I will try
It's common knowledge, it seems, that MySQL without transactions will be
a lot faster than Postgres on Inserts. And on Updates too, that is, unless
you have more than a few concurrent concurrent connections, at which point
the MySQL full table lock will just kill everything. And you don't
