Applied the straightforward parts. I left out the changes like

> +               appendBinaryStringInfo(&collist, buf.data, buf.len);

because they're not an improvement in readablity, IMHO, and they were 
not in performance-critical paths.

I also noticed that the space after "CREATE EVENT TRIGGER <name>" in 
pg_dump was actually spurious, and just added a space before newline. I 
removed that space altogether,
