The best way to handle this is to clear the unused portion of the WAL file
and then compress it before sending over the link. There is a utility
named pg_clearxlogtail available at
http://www.2ndquadrant.com/replication.htm that handles the first part of
that you may find useful here.
This reminds me yet again that pg_clearxlogtail should probably get added
to the next commitfest for inclusion into 8.4; it's really essential for a
WAN-based PITR setup and it would be nice to include it with the
distribution.
