Need help with search-and-replace

Folks,

I need to strip certain columns out of my pgdump file. However, I
can't figure out how to use any Unix-based tool to search-and-replace a
specific value which includes a tab character (e.g. replace "{TAB}7
00:00:00" with "" to eliminate the column).

RIght now, I'm copying the file to a Win32 machine and using MS Word
for the search-and-replace, but I'm sure there's got to be a better way
... *without* learning VI or Emacs. Help?

-Josh
