Check out string operators like rpad and maybe even overlay in
http://www.postgresql.org/docs/current/static/functions-string.html , the
date/number formatting operations in
http://www.postgresql.org/docs/current/static/functions-formatting.html ,
and note that you can combine strings with || in between them.
You can do something like this:
select rpad(field1,5) || rpad(field2,5) || rpad(field3,5) from table1
To get back a string formatted the way you describe. You may have to
tweak that to get the formatting on the fields exactly right. Will be
kind of brute force and fragile if anything changes, but it should work if
you tinker enough.
