Usage

omni_id: Identity types

The omni_id extension introduces custom identity types that prevent comparison errors between different ID types, catching bugs at query time.

Create an Identity Type

CREATE EXTENSION omni_id;
SELECT identity_type('user_id');

This creates a user_id type backed by bigint (default) with an auto-created sequence and constructor function.

Parameters

Auto-Generated Functions

• user_id(1) – Constructor
• user_id_nextval() – Get next value
• user_id_currval() – Get current value
• user_id_setval(user_id, bool) – Set value
