Hi, I have a question about PgSQL. I am working at some project and I want to have few tables with special properties: There would be many rows and these would be changed every day for many times. I want to be able to get know how did the row looked in given time (f.e. 2 day ago, 6 minutes ago, 2nd Sept. 2002,...). Nevertheless it should work with diffs (f.e. if I had a row with 100MB string and I changed only 2 chars it should not require on disk 200MB but only 100MB + few (kilo)Bytes). Is there any possibility how to solve it? I have heard that I can do it with triggers (but the worst thing is how to implement diffs) but I hope that there is any other (easier) way.
