Remove intarray extension. 2. Move intarray extension to a schema that's not in your search path. 3. Create an index using intarray's opclass, instead of or in addition to the core-opclass index. 4. Rename intarray's && operator to something else (will bite you at next dump/reload, where the renaming will be lost). 5. Always schema-qualify references to the core && operator. All of these have obvious downsides, especially if you're actively using the intarray extension for other purposes. regards, tom lane
