Not sure you'd notice much of a speed difference - in most cases other
overheads will be the deciding factor. Of course, YMMV.

Strange or not, it's your database and you're the only one in a position to
make this sort of decision.

I did think that it was the psql front-end that did the HTML stuff. But -
there seems to be html stuff in fe-print.c (src/interfaces/libpq) and the
Perl module Pg has html output options in $result->print(...) which might be
flexible enough for your needs.

I must admit I've never used it, so I don't know if you can add attributes
to table elements, use styles etc.
