psql \dTS+ shows for data type 'name':

pg_catalog | name | name | 64 | |
| 63-character type for storing system identifiers

I believe this is really 63 bytes, not characters. I also see it
mismatched in our docs:

in the internal system catalogs and is not intended for use by the general user. Its
length is currently defined as 64 bytes (63 usable characters plus
----------
terminator) but should be referenced using the constant
<symbol>NAMEDATALEN</symbol> in <literal>C</> source code.

Should I fix this?

Fix applied; no catalog bump.
