The merge records what it had to discard in the survivor's notes, and
search did not look there - so the value was retained and unfindable,
which answers the letter of "nothing is lost" and not the point of it. A
customer reached by their old number is exactly who somebody is looking
for when they type it.
Caught in the same patch: I wrote ESCAPE with two backslashes where the
four clauses beside it use one. In a Go raw string that is two literal
backslashes, and Postgres requires the escape to be a single character -
it would have failed the whole customer search at runtime, on a query no
in-memory test executes. All five clauses are identical now.
