Hello,
I was looking into using hardlinks to reduce the storage of keeping and syncing periodic database dumps when they are identical. This works fine with the textual format, but not for the custom format because the file header includes a timestamp set by function WriteHead in file "src/bin/pg_dump/pg_backup_archiver.c".
In order to circumvent this issue, I would think of adding a "--no-timestamp" option to pg_dump and put zeros everywhere in place of the actual timestamp in such case, and possibly ignoring the said timestamp in function ReadHead.
Any thoughts about this? -- Fabien. -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
