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:
