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?
