The previous discussion of automatic partition creation [1] has
addressed static and dynamic creation of partitions and ended up with
several syntax proposals.
In this thread, I want to continue this work.
Attached is PoC for static partition creation. The patch core is quite

Ah, nice. I didn't realize that we'd added that. But I

Hello Anastasia,
My 0.02 €:
The patch implements following syntax:
CREATE TABLE ... PARTITION BY partition_method (list_of_columns)
partition_auto_create_clause
where partition_auto_create_clause is
CONFIGURATION [IMMEDIATE| DEFERRED] USING partition_bound_spec
and partition_bound_spec is:
