Hi Keith,
Namespaces do matter because unless the opr is in the search path then
it won't be found, and even then, if there are 2 in different schemas
then the search path will determine which is to be used unless they are
qualified (ie. OPERATOR(pg_catalog.+) ).
Query looks OK at a cursory examination.
Regards, Dave.
