Hi, I happenned to come across the following in the documentation on WAL implementation in v7.1 - ***************************************************** Before WAL, any crash during writing could result in: 1.index tuples pointing to non-existent table rows 2.index tuples lost in split operations 3.totally corrupted table or index page content, because of partially written data pages ***************************************************** Does anybody know what kind of a problem this refers to ? Does this mean that incomplete transactions would be stored or does this mean that the entire table might get corrupted and unusable, implying loss of all data ? ( I am using postgresql v7.0.x , and would ideally like to migrate to v7.1 after a few months ... unless it is critical enough to do so earlier. ) Thanks, Rini __________________________________________________ Do You Yahoo!?
