OK, I found them in one of our databases. Based on the oprcode values, they seem to be related to an extension we have installed (pgsphere, in case anyone is curious). Probably from an old version of the extension, I'm guessing, as the current pgsphere passes all regression testing. So how do I clean up these dangling operators? Is it as easy as the following? DELETE FROM pg_operator WHERE oprcom IN (2234078, 2234199) OR oprnegate IN (2234078, 2234199); Thanks, Ed
