Michael Paquier d497093cbe pg_waldump: Add --save-fullpage=PATH to save full page images from WAL records ... This option extracts (potentially decompressing) full-page images included in WAL records into a given target directory. These images are subject to the same filtering rules as the normal display of the WAL records, hence with --relation one can for example extract only the FPIs issued on the relation defined. By default, the records are printed or their stats computed (--stats), using --quiet would only save the images without any output generated. This is a tool aimed mostly for very experienced users, useful for fixing page-level corruption or just analyzing the past state of a page, and there were no easy way to do that with the in-core tools up to now when looking at WAL. Each block is saved in a separate file, to ease their manipulation, with the file respecting <lsn>.<ts>.<db>.<rel>.<blk>_<fork> with as format. For instance, 00000000-010000C0.1663.1.6117.123_main refers to: - WAL record LSN in hexa format (00000000-010000C0). - Tablespace OID (1663). - Database OID (1). - Relfilenode (6117). - Block number (123). - Fork name of the file this block came from (_main).
