Yes, granting CREATE on the schema is the proper remedy for that error.

Seems that the user is trying to create a partition for a table that it doesn't own.
You must be the owner of a table to create a new partition for it.
If that happens during regular operation, your only choice will be to make the
application user the owner of the partitioned table (or a member of the owner).
I guess you cannot modify the application code, right?
Yours,
