What makes this skill specific to PostgreSQL 18?

This skill enforces features introduced or improved in PG18, such as the native uuidv7() function, the new Asynchronous I/O (AIO) subsystem, and native support for virtual generated columns.

Can this skill help with complex data auditing?

Yes, it provides patterns for bi-temporal data modeling using SQL:2011 temporal constraints, allowing you to track both validity time and transaction time accurately.

Does it help with database migration safety?

Yes, it includes standardized templates for safe schema changes, batch updates for backfilling data, and instructions for creating indexes concurrently to avoid table locks.

Why does it prefer UUIDv7 over UUIDv4?

UUIDv7 is time-ordered, which significantly improves index performance and reduces page splits compared to the random nature of UUIDv4, while remaining safe for distributed systems.

Database Management

Enforces PostgreSQL 18 best practices for schema design, migrations, and high-performance database architecture.

About

The PostgreSQL 18 Architecture skill optimizes database development by leveraging the latest engine features, including the Asynchronous I/O (AIO) subsystem, native UUIDv7 support, and SQL:2011 temporal constraints. It ensures Claude applies opinionated patterns for zero-downtime migrations, efficient indexing strategies like B-tree skip scans, and modern schema designs. By automating the application of version-specific nuances, this skill helps developers build scalable, bi-temporal, and high-performance data layers while avoiding deprecated extensions and legacy patterns.
