The SQL adapter's createDocuments() unconditionally casts boolean values to
integers (line 2518 in SQL.php), but PostgreSQL rejects int values for native
BOOLEAN columns. The single-document path already has an instanceof check to
preserve booleans for Postgres, but createDocuments() was missed.
This patch applies the same fix via a PHP script run during Docker build.
Fixes 26 test failures across PostgreSQL Legacy, TablesDB, and GraphQL suites.
