PhoenixKit V06 Migration: Allow NULL Expiration Dates for Referral Codes
This migration allows referral codes to have no expiration date by making the expiration_date field nullable. This enables the creation of permanent referral codes that never expire.
Changes
Referral Codes Enhancement
- Modifies expiration_date column to allow NULL values
- Enables creation of permanent referral codes
- Maintains backward compatibility with existing dated codes
- Supports "never expires" functionality
PostgreSQL Support
- Supports PostgreSQL prefix for schema isolation
- Safe column modification with rollback support
