It says the OID is returned, but where? I don't see it in psql.

Update with this text:
This represents the last time the snapshot files was written to
the file system.

Sure, updated paragraph:
The remote snapshot must have been exported by
<function>pg_export_snapshot()</> or been defined when creating
a logical replication slot. This can be used by parallel
<application>pg_dump</> to use a consistent snapshot across
<application>pg_dump</> processes.

OK, new text:
This allows external tools to more easily track what blocks
are modified.

That feels redundant to the major description of the item.

OK, merged into the existing item:
Add icons to all <productname>MSVC</>-built binaries and version
information to all <systemitem class="osname">MS Windows</>
binaries (Noah Misch)

Uh, do we actually want to document that API for users? I didn't think so.

Same question. I am happy to mention it, but if we mention it, we are
encouraging people to use it.
