If I'm reading that right, that isn't a SQL-level operator but an operator
in their text search query language, which would only appear in SQL
queries within string literals (compare tsquery's query operators in PG).
So it wouldn't be a hazard for ?-substitution, as long as the substituter
was bright enough to not change string literals.
