Technically speaking looking at the index alone should be enough (PG uses a unique index to enforce a unique constraint) but I added this for completeness, since we specifically want to create a constraint.

JOIN pg_attribute a ON a.attrelid = i.indrelid
AND a.attnum = ANY(i.indkey)
WHERE i.indrelid = '${newTable.name}'::regclass
AND i.indisunique;
` }
)
