Wait a minute. Are we saying there are three (3) dueling patches for adding an alternate TOAST algorithm? It seems like there is: This "custom compression methods" thread - vintage 2017 - Original code by Nikita Glukhov, later work by Ildus Kurbangaliev The "pluggable compression support" thread - vintage 2013 - Andres Freund The "plgz performance" thread - vintage 2019 - Petr Jelinek Anyone want to point to a FOURTH implementation of this feature? I guess the next thing to do is figure out which one is the best basis for further work. -- Robert Haas EnterpriseDB: http://www.enterprisedb.com The Enterprise PostgreSQL Company
