I converted a large MySQL DB to PostgreSQL in 2004 and never looked back. Think about how many improvements have occurred in Pg releases since that time and the availability of information. It took my team about six months to do the conversion as there were any number of type conversion problems due to programming assumptions and loose typing in MySQL at that time. There's also an excellent support community on IRC at Freenode (you can google it) and they are very helpful to people of any level of experience. Optimizations as presented by many are not needed right up front and you'll learn them as you go along. Good luck!
