postgresql'rs-
i've looked through to docs a bit, but have not found a way to quickly
calculate the maximum fieldwidth of each field in a tuple set. i'd like to be
able to do something like :
select field_widths(*) from relation;
where 'field_width' means the width as printed out by the default to_char()
method.
obviously psql does something internally to do it's formatting, but whatever
it does is very fast... any ideas?
