1. Identify the source of the PostgreSQL 23502 error:

SELECT * FROM pg_stat_activity;

2. Check the table definition for the table in question:

\d

3. Check the data types of the columns in the table:

SELECT column_name, data_type FROM information_schema.columns WHERE table_name = '';

4. Check the data types of the values being inserted into the table:

SELECT * FROM ;

5. If the data types of the values being inserted do not match the data types of the columns in the table, modify the data types of the values to match the data types of the columns:

ALTER TABLE  ALTER COLUMN  TYPE ;

6. Re-run the insert query to ensure the data is being inserted correctly:

INSERT INTO  VALUES (, , ...);

7. Use an automated database observability tool to monitor and fix PostgreSQL 23502 errors in the future. Automated database observability tools can detect and alert on PostgreSQL 23502 errors, as well as provide insights into the root cause of the error. This can help to quickly identify and fix PostgreSQL 23502 errors in the future.
