/**
 * Database admin operations.
 *
 * Pure, dialect-agnostic, RAW/UNSCOPED helpers backing the Supabase-Studio-like
 * DB admin. These run the FULL database with no per-user `accessFilter`
 * scoping. Callers MUST gate access before invoking them. The built-in core
 * route gates this to dev + localhost; production-reachable surfaces must pass
 * an explicit runtime for the target database and enforce their own admin-only
 * checks before reading or mutating.
 *
 * All access goes through the unified `getDbExec()` client, which uses `?`
 * placeholders (auto-converted to `$1,$2,…` for Postgres) and returns rows
 * keyed by column name. Identifiers are validated against a strict pattern and
 * always double-quoted; values are ALWAYS parameterized — never interpolated.
