That's because you don't use the unaligned format to get the
list of results. You should add -A to psql options.

Or better yet, use a simpler method that does not use
shell variables at all and work with a single psql call:

$ psql -U postgres -d postgres <<EOF

select format('GRANT CONNECT ON DATABASE %I TO cpupdate',
    datname) FROM pg_database WHERE <insert conditions here>
\gexec

EOF

That's possible because you don't need to be connected to
a database to grant the right to connect to that database.
