A few places that access this catalog don't set up an active snapshot before potentially accessing its TOAST table. However, roname (the replication origin name) is the only varlena column, so this is only a problem if the name requires out-of-line storage. This commit removes its TOAST table to avoid needing to set up a snapshot. It also places a limit on replication origin names so that attempts to set long names will fail with a more user-friendly error. Those chosen limit of 512 bytes should be sufficient to avoid "row is too big" errors independent of BLCKSZ, but it should also be lenient enough for all reasonable use-cases. Bumps catversion.
