No. The "\d+;" is taken as a backslash command, and is executed.
The rest of what you typed is still waiting in the query buffer.
It's bit weird perhaps, since \d seems like a "do-something"
command rather than a query buffer editing command. But
psql uses the same rules for both cases.

Yes, i have used it for a long, but it was always wellformed, so malformed
query was some kind of surprise.
select format('insert into x.y ( field, ... ) select val, ... from %I.%I on
conflict ( constraint ) do nothing;\dti+ x.y*', (regexp_match(tablename,
'\d[\d_]+$'))[1], schemaname, tablename) from pg_tables where schemaname =
'x' and tablename ~ '^y' order by 1;
insert into x.y ( field, ... ) select '2020_07_29'::date, field, ... from
x.y_archive_2020_07_29 on conflict ( constraint ) do nothing;\dti+
