[GENERAL] simple installation problem in windows system

[Long Cui]

I install PostgreSQL 8.3.3 in Windows XP, and set Path environment viarable
to C:\Program Files\PostgreSQL\8.3\bin, when I enter "create database mydb;"
it successed, however when "createdb mydb;" told me syntax error. Dose the
Path set wrong or I need to set other viarables?
