There are tabs all through the regression test files, and we're certainly
not going to remove them all. (If we did, we'd lose test coverage of
whether the parser accepts tabs as whitespace.) So I can't get excited
about removing one or two.
The usual recommendation for pasting text into psql when it contains
tabs is to start psql with the -n switch to disable tab completion.
