Update: Ah, didn't see your update in time. Good, we seem to (more or less) agree then :) /Update

No, you are still mistaken (or, just possibly, do not put forward your point clearly enough).

Let's read what's on the page that you mentioned:

https://www.postgresql.org/docs/current/static/sql-altertable.html

It says: 

CLUSTER ON

    This form selects the default index for future CLUSTER operations.
+ It does not actually re-cluster the table.

So it says: 'future CLUSTER operations'. That means the next CLUSTER command. That is the CLUSTER ON command. On the html-page, that CLUSTER is actually a link into sql-cluster.html. This is the CLUSTER I was talking about all along (naturally, as there is no other CLUSTERing in postgres).

So no, Postgres does not have clustered indexes, except in the sense of the CLUSTER ON command (which re-organises the underlying table on the basis of a /single/ index; and which is non-persistent (as you rightly say))
