I just noticed that PostgreSQL was listed as a user on my Macbook Pro running Lion. I have no idea how it got there and I just deleted the account. But I'm just wondering how that account could have been added without my knowledge? I had to google PostgreSQL to even find out what it is. Is this something I should be concerned about (someone trying to access my computer?) or did I just do something stupid? If this info helps... I'm running Lion since the day it released on a 15" MacBook Pro. I have Adobe CS 4 & Final Cut Pro on here... iTeleport (VNC App)... I appreciate the help!
