Short Description
vacuum analyze fails with latest cvs version

Long Description
I have a table ('messages') of email messages (subject, sender etc..) which
has a column (of type 'text') that contains the actual body of the
messages. Some of these messages are longer than 8KB so the TOAST
thing is being used.
Problem 1: "vacuum messages;" works but "vacuum analyze messages;"
kills the backend. Vacuum analyze worked (afaik) at least a month ago.
Problem 2: "cluster messages_index on messages" fails on message:
ERROR: Tuple is too big: size 29704, max size is 8136
The latter problem has existed as long as TOAST support has existed,
to my experience. (Linux, RH 7.0, i386)
