It seems to me that if the plan is to have one option structure for each index AM, which has actually the advantage to reduce the bloat of each relcache entry currently relying on StdRdOptions, then we could have those extra assertion checks in the same patch, because the new macros are introduced. > Do you know way how to distinguish one index from another?

There is rd_rel->relam. You can for example refer to pgstatindex.c which has AM-related checks to make sure that the correct index AM is being used. -- Michael
