It's just past feature freeze, so the earliest release this could appear
in is 17, about 15 months away.
Once stuff gets added to core, it's tied to the release cycle, so no new
features in between.
Presumably people would like to use the extension in the release they
already use, without backporting.
Postgres is extensible for a reason, exactly so that we don't need to
have everything in core.
Interesting, I've never thought about this one before:
What if something is deemed to be fundamental and therefore qualify for core
inclusion,
and at the same time is suitable to be made an extension.
Would it be possible to ship such extension as pre-installed?
What was the json/jsonb story, was it ever an extension before
being included in core?
No, and the difficulty is that an in-core type and associated functions
will have different oids, so migrating from one to the other would be at
best painful.
So it's a kind of now or never decision. I think extensions are
excellent for specialized types. But I don't regard a set type in that
light.
