[Solved] Identify the error in this partition creation:CREATE TABLE logs (id INT, message TEXT) PARTITION BY HASH (id);CREATE TABLE logs_p0 PARTITION OF logs FOR VALUES WITH (MODULUS 3, REMAINDER 3); | PostgreSQL

PostgreSQL - Table Partitioning

Identify the error in this partition creation:

CREATE TABLE logs (id INT, message TEXT) PARTITION BY HASH (id);
CREATE TABLE logs_p0 PARTITION OF logs FOR VALUES WITH (MODULUS 3, REMAINDER 3);

AMissing PRIMARY KEY on partitioned table

BPartition table must have different column names

CHash partitioning requires RANGE, not HASH

DRemainder value cannot be equal to modulus

Step-by-Step Solution

Solution:

Step 1: Check remainder value validity
Remainder must be between 0 and modulus-1; remainder 3 is invalid for modulus 3.
Step 2: Confirm other options
Other options are incorrect because column names can be same, HASH is correct, and primary key is optional.
Final Answer:
Remainder value cannot be equal to modulus -> Option D
Quick Check:
Remainder < modulus in hash partitions [OK]

Quick Trick: Remainder must be less than modulus [OK]
