From 6aab69e3196e2e15b679050e2db2fc9907624715 Mon Sep 17 00:00:00 2001 From: dilipkumar Date: Tue, 8 Sep 2020 15:24:33 +0530 Subject: [PATCH v21 1/7] Built-in compression method Add syntax allowing a compression method to be specified. As of now there is only 2 option for build-in compression method (pglz, lz4) which can be set while creating a table or adding a new column. No option for altering the compression method for an existing column. Dilip Kumar based on the patches from Ildus Kurbangaliev. Design input from Robert Haas and Tomas Vondra.
