    I have a batch of unstructured PDF documents and want every piece of text inside them pulled out and inserted into an SQL database. I do not need the original layout, fonts, or styling—just clean, plain-text content mapped to sensible fields (e.g., file name, page number, extracted text). Your task is to create a repeatable workflow or script that: • Reads each PDF, handles multipage files, and copes gracefully with occasional scan-quality variations. • Outputs the raw text into an SQL-ready structure and populates a database I can query immediately after the job is done (MySQL or PostgreSQL are both fine—I’ll match whatever you choose). • Includes clear setup instructions so I can run the process again on new PDFs without extra help.
