1. Identify the root cause of the PostgreSQL 0LP01 error:

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

2. Terminate the idle transaction:

SELECT pg_terminate_backend(pid) FROM pg_stat_activity WHERE state = 'idle in transaction';

3. Check the status of the PostgreSQL 0LP01 error:

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

4. If the error persists, restart the PostgreSQL server:

sudo service postgresql restart

5. Monitor the PostgreSQL server for any further errors:

SELECT * FROM pg_stat_activity;

6. Use an automated database observability tool to monitor and fix the PostgreSQL 0LP01 in question. Automated database observability tools can provide real-time insights into the performance of the database, allowing for quick identification and resolution of any issues. They can also provide alerts when any errors occur, allowing for quick resolution of the issue.
