..but these seem to be more pivot table functions that alter the data,
rather than displaying it differently. Not sure if this method is adaptable
but I may have a go.

To me swapping would be better suited as an option to psql. After all,
calling columns 'columns' in sql is aribtrary - they could just as easily
have been called rows or something else, so there's no reason for the output
to be fixed that way. Although that would chew a lot of memory if you have a
lot of records as you would need to read every record before formatting..and
I guess that explains why it hasn't been done.

No idea if this can be done in other clients!
