I prefer to use widely-used syntax instead of postgres original one.
Oracle and MySQL already use "LESS THAN" and "IN" for partitioning.
I assume almost all user only use the default operators.
I don't want to break de facto standard for small utilization area.

I think truly what we want is a new partition "kind" in addition to
RANGE and LIST. If we want to split geometric data into paritions,
we need to treat the the partition key with gist-list operation.
I agree with a plan to add some additional parition kinds,
but want to keep RANGE and LIST partitions in the current syntax.
