Tom, Thanks for the quick response. Unfortunately, I'm not able to upgrade to 12.8 at this time. I am running on AWS RDS, whichonly supports up to 12.7. I may be able to upgrade from 12.5 to 12.7 sometime in the not-to-distant future, but itcertainly won't happen for at least a few weeks. I did get a look at the server log, and I captured this which may be of interest. It seems to indicate that there was asegmentation fault in a server process: 2021-08-16 11:14:23 UTC:XX.XXX.XX.XXX(60984):user1@dbserver001:[26547]:LOG: AUDIT: SESSION,1,1,DDL,CREATE PROCEDURE,PROCEDURE,user1.proc(charactervarying),"CREATE OR REPLACE PROCEDURE proc ( a_string INOUT VARCHAR ) AS $$ << proc >> DECLARE val BIGINT; BEGIN COMMIT; SELECT 0 INTO val; END proc; $$ LANGUAGE PLPGSQL;",<none> 2021-08-16 11:14:23 UTC:XX.XXX.XX.XXX(60984):user1@dbserver001:[26547]:LOG: AUDIT: SESSION,2,1,DDL,CREATE PROCEDURE,PROCEDURE,user1.proc_caller(),"CREATEOR REPLACE PROCEDURE proc_caller() AS $$ << proc_caller >> DECLARE some_string VARCHAR := 'some_string'; BEGIN CALL proc(some_string); END proc_caller; $$ LANGUAGE PLPGSQL;",<none> 2021-08-16 11:14:23 UTC:XX.XXX.XX.XXX(60984):user1@dbserver001:[26547]:LOG: AUDIT: SESSION,3,1,FUNCTION,EXECUTE,FUNCTION,user1.proc_caller,CALLproc_caller();,<none> 2021-08-16 11:14:23 UTC:XX.XXX.XX.XXX(60984):user1@dbserver001:[26547]:LOG: AUDIT: SESSION,3,2,FUNCTION,EXECUTE,FUNCTION,user1.proc,CALLproc_caller();,<none> 2021-08-16 11:14:23 UTC:XX.XXX.XX.XXX(60984):user1@dbserver001:[26547]:LOG: AUDIT: SESSION,3,3,READ,SELECT,,,SELECT 0,<none> 2021-08-16 11:14:23 UTC::@:[26543]:LOG: server process (PID 26547) was terminated by signal 11: Segmentation fault 2021-08-16 11:14:23 UTC::@:[26543]:DETAIL: Failed process was running: CALL proc_caller(); 2021-08-16 11:14:23 UTC::@:[26543]:LOG: terminating any other active server processes 2021-08-16 11:14:23 UTC::@:[4300]:WARNING: terminating connection because of crash of another server process 2021-08-16 11:14:23 UTC::@:[4300]:DETAIL: The postmaster has commanded this server process to roll back the current transactionand exit, because another server process exited abnormally and possibly corrupted shared memory. 2021-08-16 11:14:23 UTC::@:[4300]:HINT: In a moment you should be able to reconnect to the database and repeat your command. 2021-08-16 11:14:23 UTC::@:[26543]:LOG: archiver process (PID 4301) exited with exit code 2 2021-08-16 11:14:23 UTC::@:[26543]:LOG: all server processes terminated; reinitializing 2021-08-16 11:14:23 UTC::@:[26548]:LOG: database system was interrupted; last known up at 2021-08-16 11:13:42 UTC 2021-08-16 11:14:23 UTC::@:[26548]:LOG: database system was not properly shut down; automatic recovery in progress 2021-08-16 11:14:23 UTC::@:[26548]:LOG: redo starts at 403/C00007F8 2021-08-16 11:14:23 UTC::@:[26548]:LOG: invalid record length at 403/C400CD78: wanted 24, got 0 2021-08-16 11:14:23 UTC::@:[26548]:LOG: redo done at 403/C400CD10 2021-08-16 11:14:23 UTC::@:[26548]:LOG: checkpoint starting: end-of-recovery immediate 2021-08-16 11:14:23 UTC::@:[26548]:LOG: checkpoint complete: wrote 11 buffers (0.0%); 0 WAL file(s) added, 0 removed, 1 recycled;write=0.007 s, sync=0.003 s, total=0.023 s; sync files=4, longest=0.003 s, average=0.000 s; distance=65585 kB, estimate=65585kB 2021-08-16 11:14:23 UTC::@:[26543]:LOG: database system is ready to accept connections Thanks, Chuck -----Original Message----- From: Tom Lane <tgl@sss.pgh.pa.us> Sent: Monday, August 16, 2021 7:48 AM To: Chuck Nellis <crnellis@raytheon.com> Cc: pgsql-bugs@lists.postgresql.org Subject: [External] Re: psql crash when running a procedure with an inout parameter and a commit Chuck Nellis <crnellis@raytheon.com> writes: > I'd like to report a bug I encountered while running psql on PostgreSQL version 12.5, on RHEL 7.9.
