def extract_text_from_pdf(pdf_data: bytes) -> Dict[str, any]:
    """
    Extract text content from a PDF file with metadata and page information
    """
    pdf_document = fitz.open(stream=pdf_data, filetype="pdf")
    metadata = pdf_document.metadata
    page_count = len(pdf_document)
    # ... text extraction logic
