I've open a 54MiB .sql file with gedit 2.30.4 (Ubuntu 11.04) and no problem. There is now a progress bar.
But there are some lines with near 300000 columns where the editor doesn't scroll text when the user walks with the keyboard cursor to the first or the last characters, and with "text wrapping" it refreshes poorly the work area when Search&Replace.
