Alvaro Herrera c2e0954be3 Relax overly strict assertion ... Ever since its birth, ReorderBufferBuildTupleCidHash() has contained an assertion that a catalog tuple cannot change Cmax after acquiring one. But that's wrong: if a subtransaction executes DDL that affects that catalog tuple, and later aborts and another DDL affects the same tuple, it will change Cmax. Relax the assertion to merely verify that the Cmax remains valid and monotonically increasing, instead. Add a test that tickles the relevant code.
