Currently, test_slru's shmem_startup_hook unconditionally generates new LWLock tranche IDs. This is fine on non-EXEC_BACKEND builds, where only the postmaster executes this hook, but on EXEC_BACKEND builds, every backend executes it, too. To fix, only generate the tranche IDs in the postmaster process by checking the IsUnderPostmaster variable. This is arguably a bug fix and could be back-patched, but since the damage is limited to some extra unused tranche IDs in a test module, I'm not going to bother.
