Subject: Urgent: Segmentation Fault in PostgreSQL postmaster Process

 

Dear Team,

 

I am experiencing a segmentation fault issue with the postmaster process of our PostgreSQL database, and I am seeking your assistance. Below are the details of the error and our system configuration.

 

Issue Description

We encountered a segmentation fault in the postmaster process of our PostgreSQL instance. The relevant system log entry is as follows:

 

DB Logs:

LOG:  restartpoint starting: time

LOG:  startup process (PID 21704) was terminated by signal 11: Segmentation fault

LOG:  terminating any other active server processes
