PostgreSQL 42602

INVALID NAME error message indicates that the specified name is invalid or does not exist in the database. This error is usually caused by a typo or incorrect syntax.

How It Affects Your App

The PostgreSQL 42602 INVALID NAME error indicates that the database has encountered an invalid name when attempting to execute a query. This can have a significant impact on an application, as it can prevent the application from executing queries and retrieving data from the database. This can lead to the application not functioning properly, or even crashing. Additionally, the application may not be able to access the data it needs, leading to unexpected results or errors.

How To Fix

1. Identify the source of the PostgreSQL 42602 error:

SELECT * FROM pg_stat_activity WHERE state = 'idle in transaction'

2. Check the application code for any open transactions that are not being closed properly:

SELECT * FROM pg_stat_activity WHERE state = 'active'

3. If any open transactions are found, close them manually:


4. If the issue persists, check the PostgreSQL logs for more information:

SELECT * FROM pg_log

5. If the issue is still not resolved, restart the PostgreSQL server:

sudo service postgresql restart

6. Finally, to prevent future occurrences of PostgreSQL 42602, use an automated database observability tool to monitor and fix the PostgreSQL server. This tool can provide real-time insights into the performance of the database, detect any issues, and alert the user when an issue arises. This can help to quickly identify and fix any issues before they become a major problem.
