PostgreSQL Table Design FAQs

Question 1

How does this skill handle time-series or large-scale data?

Accepted Answer

It provides strategies for declarative partitioning (RANGE, LIST, HASH) and recommends BRIN indexes for very large, naturally ordered data sets to minimize storage overhead.

Question 2

What is the recommended primary key type for PostgreSQL?

Accepted Answer

The skill recommends using BIGINT GENERATED ALWAYS AS IDENTITY for most tables. It suggests UUIDs only when global uniqueness or opacity is required for distributed systems.

Question 3

Can it help with JSONB and semi-structured data?

Accepted Answer

Absolutely. It provides guidance on when to use JSONB over traditional relational columns and how to effectively index JSONB content using GIN indexes for containment and existence queries.

Question 4

Does this skill handle foreign key indexing?

Accepted Answer

Yes, it specifically highlights that PostgreSQL does not auto-index FKs and provides the necessary implementation patterns to add them manually to speed up joins and prevent locking issues.

Question 5

Why does it recommend TIMESTAMPTZ over TIMESTAMP?

Accepted Answer

The skill follows the best practice of using TIMESTAMPTZ to ensure that all timestamps are stored in UTC and correctly converted for different time zones, avoiding common data corruption issues.
