Hi, The topic came on IRC and it might be that the later attempts at using another library missed one of the offering, namely FastLZ. It's made for being quick rather than minimize size, it's MIT licenced, 551 lines of portable ansi-C code, already tested on a host of systems and compilers.
http://www.fastlz.org/ http://www.fastlz.org/compilers.htm http://www.fastlz.org/benchmarks.htm http://code.google.com/p/fastlz/source/browse/trunk/fastlz.c Example call sites: http://code.google.com/p/fastlz/source/browse/trunk/6pack.c http://code.google.com/p/fastlz/source/browse/trunk/6unpack.c Maybe the only drawback is that it does not seem to be well maintained any more, so it could mean the code would have to be considered for inclusion into the PostgreSQL tree. Still I though I'd mention the lib. As far as the usage part is concerned, not only TOAST could benefit, but some IRC users are talking about protocol level compression. Should this one be fast enough and an option on the other grounds, how open to libpq compression are we?
