line folding versus shop line

Hi,

I'm using postgresql 7.4. If I execute SQL Select statement, then the
records fold around lines.

I would like to turn this off, so that lines do not fold.

I know the option in less, which one has to set to "-S". I have
exported the variable and it works with textfiles.

However, if I use psql then lines are folded even so the enviornment
variable of LESS is set to S.

How do I turn line folding off, so that records do not wrap around???
