Is it possible to convert a pdf file to post script, then to text for see codes used in post script?

I have one pdf file where text have been formatted in tables, boxes, background colours. I tried to convert my text file to pdf with boxes, tables and background colours with enscript. I got success for foreground and background colours, but no tables and boxes. So I converted one pdf file to post-script to see what codes had been used for creating/inserting tables and boxes with text. I got success with PS codes but these are very difficult to understand. Then I converted .ps file to text, but now I can not see codes. I am hoping after understand post-script code I will use the same with awk as usual for pdf conversion. But no success. Is there any tool or command so I can see exact code used in post-script with text editor? I am using red hat linux 5.9.
