This statement isn't correct. There are, in fact, tools for doing
incremental backup and restore with PG and they work quite well, as I
mentioned. Currently they operate at a file-level, which means 1G
chunks instead of block-level, but there is work being done to change
that too. There isn't anything in "PG technology" that makes this
impossible or, really, even that difficult, it's more that there hasn't
been effort put into it simply because the file-level incremental
solution works quite well in most cases.
Thanks!
