You are right.  I looked at the code, and "vacuumdb" does not process

partitiond tables, even if --analyze-only is specified.  I find that

surprising, aince the SQL command ANALYZE (without a table name) will

also collect statistics for partitioned tables.



I think that it would be a good idea to change that behavior.

In particular, it makes a lot of sense to collect statistics for

partitioned tables after a "pg_upgrade".



Attached is a patch to make "vacuumdb --analyze-only" consider

partitioned tables as well.



Yours,

Laurenz Albe



Is there a plan to include this patch in future releases/patches of postgres?



Thanks,
