smgrrelease() and smgrzeroextend() dispatch through smgrsw[reln->smgr_which] instead of reln->smgr, so an f_smgr installed by smgr_hook is silently bypassed. Both arrived with the REL_16_9 merge in upstream form; every other entry point in smgr.c already goes through reln->smgr. smgrrelease() is harmless for the in-tree managers. smgrzeroextend() is not: it is the bulk-extension path from ExtendBufferedRelShared(), and reaching mdzeroextend() unhooked makes register_dirty_segment() tag the checkpointer fsync request with the un-redirected path. That file never exists, so the next checkpoint PANICs with "could not fsync file ...: No such file or directory" and the segment enters a crash/restart loop. Nothing changes when no hook is installed, since smgropen() sets reln->smgr to &smgrsw[reln->smgr_which].
