How It Affects Your App
The PostgreSQL 42P07 DUPLICATE TABLE error indicates that a table with the same name already exists in the database. This can have a significant impact on an application, as it can prevent the application from creating new tables or modifying existing ones. It can also lead to data corruption, as the application may attempt to write to the wrong table. Additionally, it can cause queries to fail, as the application may attempt to query the wrong table.

2. Check the table definition to ensure that the unique constraint is properly defined:
3. Check the data being inserted to ensure that it is unique:
4. If the data is not unique, update the existing record instead of inserting a new one:
5.

This tool can provide real-time alerts when the error occurs, allowing for quick resolution of the issue. Additionally, the tool can provide detailed insights into the root cause of the error, allowing for more efficient debugging and resolution.
