If we're going to do work in this area, why wouldn't we have the client
tools and the server agree on the max length and then have them all be
consistent..?

Seems odd to decide that 100 character buffer size in the clients makes
sense and then make the server support an 8k password.

I'm also trying to figure out why it makes sense to support an 8k
password and if we've really tried seeing what happens if pg_authid gets
a toast table that's actually used for passwords...

I'll note your patches neglected to include any tests...

Thanks!
