// Batch variant of CreateTaskMessage: persists a whole daemon-reported batch in
// ONE statement — therefore one round trip and, more importantly, one commit
// instead of one per message. Commit acknowledgement (IO:XactSync) is ~94% of
// this SQL's load in production, so the commit count is the thing being
// optimized; the round trip is a bonus.
//
// The rows arrive as parallel arrays rather than as one jsonb document, even
// though a jsonb document is the tidier Go side. content and output routinely
// carry tens of KB and occasionally megabytes, and wrapping them in JSON makes
// the server escape every byte a second time and Postgres parse the whole
// envelope back out — measured at 1.2x the old per-row insert at 128KB and
// ~1.8x at 1MB, i.e. a regression on exactly the most expensive requests, which
// are also the ones least likely to be batched. Native text[] elements are
// length-prefixed by the wire protocol, so they cost neither pass.
//
// NULLIF is what makes per-row NULL expressible through a non-nullable []string
// (the Go type sqlc gives a text[] parameter): it reproduces, exactly, the
// `pgtype.Text{Valid: x != ""}` mapping the single-row query carries — empty
// string means SQL NULL. input is passed as text and cast here for the same
// reason; it is the one column that genuinely has to be parsed as JSON, because
// it is a jsonb column. created_at also rides this transport so an older daemon
// can omit its event time and keep the database-time fallback. output_truncated
// uses the same trick because it is a genuinely tri-state boolean (NULL = the
// reporting daemon did not measure it), and a bool[] parameter becomes a Go
// []bool, which has no way to spell the third state.
//
// Callers MUST still run the Postgres text sanitizer first. A NUL anywhere in
// the batch fails the whole statement (GH #7098) — that is inherent to batching
// into one statement, not to the parameter shape.
//
// Atomicity is a deliberate side effect, not just a speedup: the per-message
// loop this replaces could persist part of a batch and then fail, leaving the
// transcript with a prefix of the batch and no way to complete it — the daemon
// does not retry this endpoint. One statement makes the batch all-or-nothing,
// which buys consistency. Callers that supply a task-scoped idempotency key
// derive a stable message UUID; the primary-key conflict below deduplicates
// retries without changing the append-only behavior of legacy random IDs.
//
// The ORDER BY is a contract, not decoration. A bare `INSERT ... RETURNING`
// has no defined row order, and the caller republishes these rows as realtime
// events in the order they arrive — the per-row loop this replaces implicitly
// published in request order, so the ordering has to be restored explicitly or
// subscribers can see a batch out of order. seq is assigned by the daemon and
// increases within a batch, so it is the request order.
