I'm looking at the new in PG18 pg_dump --with-* options, and I'm having
trouble understanding them. (I did not look into the source code or the
git or mailing list history for this, to try to understand it as a user.)
We have
-a, --data-only dump only the data, not the schema or statistics
--no-data do not dump data
--with-data dump the data # this one is new
(and there is also --section=data), and then three analogous options for
"schema" and "statistics".
What is the purpose of the --with-data option? Dumping the data is the
default. Is this to override an earlier --no-data option?
The man page is only minimally more verbose: "Dump data. This is the
default." But why do you then need this option?
I think we should add some more documenting detail for these, but right
now I don't know what it would be.
