No, I don't think that's concensus yet. If you want to make it configurable on that level you need to have: 1) compression format signature on fpws 2) mapping between identifiers for compression formats and the libraries implementing them. Otherwise you can only change the configuration at initdb time... > Also, probably we need to implement at least one compression contrib module > using that hook, maybe it's based on pglz or snappy. >From my tests for toast compression I'd suggest starting with lz4. I'd suggest starting by publishing test results with a more modern compression formats, but without hacks like increasing padding.
