From cf131fa942855acd42e8283185837566c7e8c15e Mon Sep 17 00:00:00 2001 From: Nathan Bossart Date: Tue, 25 Mar 2025 16:02:35 -0500 Subject: initdb: Add --no-sync-data-files. This new option instructs initdb to skip synchronizing any files in database directories, the database directories themselves, and the tablespace directories, i.e., everything in the base/ subdirectory and any other tablespace directories. Other files, such as those in pg_wal/ and pg_xact/, will still be synchronized unless --no-sync is also specified. --no-sync-data-files is primarily intended for internal use by tools that separately ensure the skipped files are synchronized to disk. A follow-up commit will use this to help optimize pg_upgrade's file transfer step. The --sync-method=fsync implementation of this option makes use of a new exclude_dir parameter for walkdir(). When not NULL, exclude_dir specifies a directory to skip processing. The --sync-method=syncfs implementation of this option just skips synchronizing the non-default tablespace directories. This means that initdb will still synchronize some or all of the database files, but there's not much we can do about that.
