I’m encountering a segmentation fault issue in PostgreSQL 13.4 when executing a specific function (cause_segfault()). The server process terminates with a signal 11 (Segmentation fault), but the database service continues running without a full shutdown.
Details:
• PostgreSQL Version: 13.4
• Environment: RHEL 8
• Steps to Reproduce:
1. Create function: CREATE FUNCTION cause_segfault() RETURNS void AS 'cause_segfault', 'cause_segfault' LANGUAGE C STRICT;
2. Execute function: SELECT cause_segfault();
Observations:
• Logs indicate the segmentation fault (LOG: server process (PID XXX) was terminated by signal 11: Segmentation fault).
Request for Assistance:
• Has anyone encountered similar issues with PostgreSQL 13.4?
• Are there known bugs or fixes related to segmentation faults in recent PostgreSQL versions?
• Any advice on troubleshooting or resolving this issue would be greatly appreciated.
