Here's the actual reproducer I used:

$ cat run.sql
drop database if exists test;
create database test;
\c test

\i pgdump
reset all;

alter system set log_line_prefix = '%m [%p] %q%u@%d %a ';
select pg_reload_conf();

set jit=off;
LOAD 'auto_explain';
set auto_explain.log_analyze=on;
set auto_explain.log_buffers=on;
set auto_explain.log_min_duration=0;
set auto_explain.log_nested_statements=on;
set auto_explain.log_triggers=on;

set application_name = 'collate_bug';
INSERT INTO public.identity_provider (id, created, lastmodified, "version", identity_zone_id, "name", origin_key,
"type",config, active)
 
VALUES('24e9dd6d-5a63-9ea8-b425-ae89aa419a33', CURRENT_TIMESTAMP,CURRENT_TIMESTAMP, 0, 'insert-test', 'test', 'test',
'test','none', true);
