The following documentation comment has been logged on the website:
Page: https://www.postgresql.org/docs/12/sql-analyze.html
Description:
https://www.postgresql.org/docs/12/sql-analyze.html does not have anything
about not being able to run ANALYZE on replicas.
I now understand that this is because statistics are stored in a table, and
that table is replicated from primary server to the replica, but it would be
helpful to have something about this in the official documentation.
Thanks,
Niko.

I'm a little skeptical about that. By that argument, nearly every one
of our SQL command pages would need a disclaimer saying that you can't
use it on a replica.
