I am not sure what is going on here, but skink has gone rogue since
this has been committed. The first failure of this animal points to
this commit:
https://buildfarm.postgresql.org/cgi-bin/show_log.pl?nm=skink&dt=2026-01-28%2017%3A12%3A26
Some details from postmaster.log:

**2296443** Valgrind detected 1 error(s) during execution of "declare
c1 scroll cursor for select (select 42) as x;"
So it looks like this is missing some initialization, causing valgrind
to complain.
