TBH I'm not sure that wastefully allocating NAMEDATALEN for each
relation is so great. Our strategy for easing memory management is to
use appropriately timed contexts.
I guess if you wanted to make a publication a single palloc block (so
that it's easy to free) and not waste so much memory, you could stash
the name string at the end of the struct. I think that'd be a change
wholly contained in GetPublication.
