Can mysql-server-express compress strings? if you could give me a link to some documentation that says so it will be much appreciated as I can't seem to find this info.
I know that mysql allows this by using the compress() Function on the string. Also wondering whether this can be done automatically or do you need to use this function every time?
Also according to http://www.postgresql.org/docs/8.0/interactive/datatype-character.html - the compression is done automatically. Am I correct?
