Thanks for the info and replying,
Actually I dont know more about binary files, and the link you posted, there are many files, and which ones I should download, and how can I use it? sorry for asking again.
1. unzip complete file in folder
2. carefully read readme.txt
(there are further links you should consider, especially faq. You should fully understand, how to deal with installing features BEFORE trying to install PostgreSQL)
3. run msi installer file
Postresql is a complete object-rational database system, what is also some kind of Oracle clone due to its own PL/SQL. MySql is not able to hold a candle to power PostgreSQL, entirely. Actually, it isn't that difficult to set up postgresql on win32. However, it is said that postgresql would run rather slower on win32 than an linux. I myself prefer linux.
