Hello, For a data warehousing project I will have to implement bitmaps. I would perfer to stay away from C, Java, etc., and would like to use PostgreSQL instead. I have a question about bit string type: does the time it takes to do the & or | of two bit strings run in constant time (as it does in C)? Thanks, Yasir
