Re: Slow Query problem

I already install the latest version of PostgreSQL on my machine then try again. I found that it has a little improvement about 0.5 second but I think it still slow.

What is the 'more detail' you need?

Any other advise?

One suggestion is that 8.2.x is significantly smarter about joins to
unions than previous releases were. Whether this would help in your
particular case is impossible to say, though, without more detail.

TIP 9: In versions below 8.0, the planner will ignore your desire to
choose an index scan if your joining column's datatypes do not
match
