My inclination is to fix this by removing pg_authid's toast table.
I was not in favor of "let's attach a toast table to every catalog"
to begin with, and I think this failure graphically illustrates
why that was not as great an idea as some people thought.
I also don't think it's worth trying to make it really work.
I'm also now more than just slightly skeptical about whether
pg_database should have a toast table. Has anybody tried,
say, storing a daticurules field wide enough to end up
out-of-line?
