/**
 * Admin SQL (drop / empty / truncate / clone / copy) is built in Rust from the database type alone,
 * which cannot describe a database whose quote character depends on the connection. Cloud Spanner is
 * the case that forces the connection-reported quote to be threaded through: GoogleSQL quotes with
 * backticks, its PostgreSQL dialect quotes with double quotes, and the dialect is fixed when the
 * database is created. Emitting the static answer produces admin SQL that is a syntax error for
 * every PostgreSQL-dialect Spanner database.
 *
 * These assertions pin the call sites rather than the generated SQL, because the plumbing is what
 * regressed: the backend already knew how to honour a reported quote (`data_grid_sql.rs` carries the
 * same field) and the builders simply were not given one.
