It's easy enough to get psql to output tab-separated columns to a file
from its query (see the various backslash formatting commands and \o).
Spit out the 15 different files you want to /tmp, then use a script with
COPY ... FROM /tmp/file1 etc.
If you use COPY the files need to be readable by the backend process,
otherwise look into \copy in a psql script.
If it gets much more complicated, I knock up a short Perl script. Others
probably prefer Python or Ruby.
