 Thanks much!  After much experimentation, I figured it out.  I remember
reading in the postgres oreily book that if you don't quote the identifiers,
that it converts them all to lowercase for processing.  Does the dash in the
name also require the name to be quoted?

Thanks again!

 SELECT "User-Name", max("Date"), max("Time") from logs;

Assuming the MulTiCasIng you show is also in the table. SQL lets you
put anything at all in an identifier (table or column name) as long
as you quote it with double-quotes (")
