Maybe it was fixed, but i reappear this bug in pg 15.14.

In my case ,just set compute_query_id = on in PostgreSQL.conf, then reproduce it:

1. in term1:
/opt/pg/15/bin/pgbench -p 1514 -i -s 10 pgbench
/opt/pg/15/bin/pgbench -p 1514 -T 1200 -M simple -d pgbench

2.in term2:
file .psqlrc \pset null 'NULL'
/opt/pg/15/bin/psql -p 1514 -t pgbench
Null display is "NULL".
psql (15.14)
Type "help" for help.

pgbench=# select query_id from pg_stat_activity where pid=7008;
