On the other hand, if the PDF was simply uses text fonts and vector graphics, then you can (in theory) export it (e.g. from Acrobat Reader) to a PostScript file -- just "print to file".
More usefully from the command line, there's pdf2ps (from Ghostscript) and pdftops (from XPDF and maybe Poppler).
A disappointingly high number of Windows-produced PDF files are simply bitmaps in PDF wrappers. Mac-produced ones seem better, but still much larger than most GNU-produced ones. I don't understand enough PDF to know why.
Another approach is using Perl or PHP libraries to open the PDF and stick text on it, as mentioned by others, which I've done sometimes, with good results.
Good luck!
