Use proper PostgreSQL types

Leverage PostgreSQL’s native data types and features instead of generic alternatives to improve performance, type safety, and query capabilities. Use JSONB for structured data instead of storing raw text, implement PostgreSQL enums for constrained values rather than varchar columns, and establish proper foreign key relationships with meaningful column names.

Examples:

• Store structured data as JSONB: @Column({ type: 'jsonb' }) instead of raw text for better retrieval performance and query capabilities
• Use PostgreSQL enums: @Column({ type: 'enum', enum: PreferredCalendar }) with database-level enum creation instead of varchar
• Design proper relationships: Use recordId and objectMetadataId pointing to metadata tables instead of generic objectId/objectType pairs
• Apply appropriate constraints: Mark columns as non-nullable when they have defaults: @Column({ nullable: false, default: value })

This approach enables better query optimization, data integrity, and leverages PostgreSQL’s advanced features for improved application performance.
