CacheInvalidateHeapTuple currently does the following tests first; would there
be a performance improvement to testing the system relation case first? We're
almost never in bootstrap mode, so that test is almost always a waste. Is there
any reason not to switch the two?
/* Do nothing during bootstrap */
if (IsBootstrapProcessingMode())
return;
/*
* We only need to worry about invalidation for tuples that are in
system
* relations; user-relation tuples are never in catcaches and can't
affect
* the relcache either.
*/
if (!IsSystemRelation(relation))
return;
