Hi Fellows I have a question regarding PostgreSQL 9.1 indexing. I am having a table and want to create a index for a column and I want to store the data with time zone for that column. The questions are: 1. Can I create a index for a column which store time stamp with time zone. If can is there ant performance issues? 2. Also I can store the time stamp value with zone as a long integer value. If so what is the difference between the above step. Which one is better. Many Thanks.
