You either need to be sure there are no "gaps" in your source rows
(provide one row for every category for each group, e.g. by doing an
outer join) or use the hashed version of the function. Search the README
for:

crosstab(text source_sql, text category_sql)

That is the hashed version that will do what you're looking for.

HTH,
