To make this discussion a bit more specific, I've created a patch of how it can
look like. All the arguments, except Archive, CatalogId and DumpId I've moved
into the ArchiveOpts structure. Not all of them could be empty before, but
anyway it seems better for consistency and readability. Some of the arguments
had empty string as a default value, I haven't changed anything here yet
(although this mixture of NULL and "" in ArchiveEntry looks a bit confusing).
As Andres mentioned above, for 578b229718e / the WITH OID removal and pg_dump
modification from pluggable storage thread, this patch reduces number of
changes, related to ArchiveEntry, from 70+ to just one.
