The boolean charts try to do something like: SUM(CONCAT(flagtypes_0.name, flags_0.status::varchar) != 'review+') (That's the boolean chart "Flag is not equal to review+".) However, PostgreSQL throws an error when you try to do this: "Function sum(boolean) does not exist"
Oh, by the way, ignore that "::varchar," that's a local customization. (That's not in the tip Search.pm.)
Created attachment 177663 [details] [diff] [review] V1 It turned out to be simpler than I expected - only one occurence of this problem in the whole of bugzilla :-).
