PostgreSQL INT4RANGE: Enforce non-overlapping zones in SQL

1. 1Create a table with a column of type INT4RANGE to store postal code zones
2. 2Insert sample data into the table with non-overlapping zones
3. 3Apply a GIST constraint to the column to enforce non-overlapping zones
4. 4Test the constraint by attempting to insert overlapping zones
5. 5Use the '&&' operator to check for overlapping zones between two INT4RANGE values

Database administrators and developers can benefit from this technique to efficiently manage and assign postal code zones to agents without overlap

💡 PostgreSQL's INT4RANGE and GIST constraint can be used to efficiently enforce non-overlapping zones in SQL
