Ok, I worked out the direct cause, pg_wcswidth only returns the length
upto the first newline and the line it breaks on is the multiline
definition in "_pg_expandarray".

The quick fix should be to only allocate memory if it's going to call
format_numeric_locale(), since then you know it's a number. It makes
the code slightly more convoluated but it should be slightly more
efficient.

I actually have a working psql that handles and displays newlines
properly, but it's too late for 8.1. It fixes all these issues
properly.

Have a nice day,
