That is a somewhat separate issue, but good that you bring it up. In my
cleaning ways I noticed that the -e vs. -E switches weren't applied
correctly so I set that straight to an extent. The regression tests rely
on -e to echo the query back correctly, not the one actually sent to the
backend, so that could be tweaked.

Luckily, the regression tests don't make extensive use of the backslash
commands, the issue being that their output might change. I only found
three backslash commands in the whole regression tests. One occurence does
something like this:

some query;
*** comment
*** comment
\p
\r
more queries;

which should probably be changed anyway to something like

-- comment
-- comment

The other case is
CREATE TEMP TABLE temptest(col int);  
-- test temp table deletion  
\c regression  
SELECT * FROM temptest;
which still works as I just confirmed, and the output of \c gets eaten in
-q mode anyway.

Seems it's still safe.
