That seems like a good idea. Might also make sense to make the behavior configurable via a developer-only GUC, to enable exhaustive tests that use every possible permutation of physical/logical mappings for a given table. Perhaps the random behavior itself should work by selecting a value for the GUC at various key points via a PRNG. During CREATE TABLE, for example. This approach could make it easier to reproduce failures on the buildfarm. -- Peter Geoghegan
