Oh ... what is happening, I think, is that the toast pointers are getting stored into the "baddata" local variable as-is. The problem would only get detected if the system has to fetch the toasted value, and this code doesn't make it do so. You could do something that requires fetching the value, perhaps SELECT api_response || '' INTO baddata ... regards, tom lane -- Sent via pgsql-admin mailing list (pgsql-admin@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-admin
