Subject: [PATCH] Fix README quick example: use $batch.* row-set expansion

The Quick Example used `id = ANY($batch)`, but a bare $var substitutes
only the first column of the first captured row as a scalar, so the
generated SQL was `id = ANY(1)` and failed with "op ANY/ALL (array)
requires array on right side".

Use the $batch.* row-set expansion instead, referencing the captured
result as a subquery: `id IN (SELECT id FROM $batch.*)`.
