What tasks have you managed to solve using PostgreSQL in your projects?

In projects using PostgreSQL, I have addressed tasks related to storing and processing structured data, including:

• Designing database schemas with normalization to ensure data integrity.
• Optimizing queries using indexes, including composite and full-text indexes.
• Implementing transactions to ensure atomicity of operations.
• Using JSONB for storing and processing semi-structured data.
• Setting up replication and backups to ensure fault tolerance.

For example, in one project, I implemented an order management system where I used transactions to correctly deduct items from the warehouse and create order records to avoid discrepancies.
