You can use \o in psql to redirect the result to a file.

\o out.file

If you want to get the data without being IN psql (like in an automated
script) you can use the -tc switches ("t"uples only, run this
"c"ommand):

psql dbname -tc "select yabba from dabba where doo=1" > myfile.dat

If you're in psql, use \o for output.  \i does the same thing for input
from a file.
