Tom Lane 6b516f5951 Fix performance problems in TOAST compressor. The management of ... search lists was broken in such a way that only the most recent instance of a given hash code would ever be searched, thus possibly missing longer matches further back. Fixing this gave 5 to 10% compression improvement on some text test cases. Additional small tweaks to improve speed of inner loops a little bit. There is no compatibility issue created by this change, since the compressed data format and decompression algorithm don't change.		24 years ago
