ERROR: Attribute 'processtype' is of type 'varchar' but expression is of
type 'bool'
You will need to rewrite or cast the expression
hhs=#

And

if I try to cast minority to varchar (or anything else for that matter) I
get

ERROR: Cannot cast type 'bool' to 'varchar'

Is there any way to get the above to work? I have a client down and need
this (or something like this) to straighten out his data tables... Thanks!
