You have to do it yourself, or translate the XML into an infoset-preserving form that will still allow XPath and friends.

Re: [PERFORM] Compression of text columns
Tino Wildenhain mentioned : = Well, text columns are automatically compressed via the toast mechanism. = This is handled transparently for you. OK, I misread the documentation, and I forgot to mention that I'm using postgres 7.3 and 8.0 It's actually the EXTERNAL storage type that is larger, not EXTENDED. What kind of compression is used in the EXTERNAL storage type? Is there any way to achieve better compression? ---(end of broadcast)--- TIP 6: explain analyze is your friend
