In case the PG group does get interested in insertion of compression
algorithms into PostgreSQL {it seems it could be useful in many
different areas}, the 7zip format seems to be excellent in a number of
ways.
Here is an interesting benchmark that shows 7z format winning a large
area of the "optimal compressors" performance graph:

The LZMA SDK is granted to the public domain:

Unfortunately LZOP (which wins the top half of the "optimal compressors"
graph where the compression and decompression speed is more important
than amount of compression) does not have a liberal license.
