/**
 * @personal-blog/database-postgres — EPPP PostgreSQL adapter package.
 *
 * [E00-S03-T02] this package is the single owner of the PostgreSQL driver
 * stack: it is the only workspace package allowed to import `pg` and Kysely.
 * Every piece of the workspace that talks to the database goes through this
 * boundary — the pool, the query builder dialect and the adapter API this
 * package will expose — so no other package ever imports the driver directly.
 *
 * This module is the driver boundary: it imports the PostgreSQL driver (`pg`)
 * and Kysely and re-exports the pieces the adapter is built on — the driver
 * surface (E00-S03-T02), the migration ledger (E00-S03-T03) and the migration
 * advisory lock (E00-S03-T04). The failure diagnostic (E00-S03-T05) lands in
 * a later story; until then the re-exports keep the driver reachable only
 * from here — the isolation is real, not a placeholder.
