Обсуждение: Strange error message with 7.0beta1

When trying to load my data from a 6.5 pg_dump, I got the error message:

psql:/tmp/ati-tmp.sql:87: ERROR:  Tuple is too big: size 8164, max size
8140

I trimmed back the dump file to a minimum of these commands that will
still generate the error:

        WHERE ("e"."etype" = 'p'::"varchar")
        AND ("e"."expnum" = "w"."expnum");

As the SQL was generated by a previous copy of PostgreSQL, I figured it
might be a problem with the 7.0beta1.

Any ideas?

Due to some internal changes the rule descriptor (so to speak) has
expanded in its size so now it doesn't fit within a tuple anymore. There
were some changes done in this area just the other day, so you might want
to get a later beta and try it out. (I think they make these every night.)

Get the snapshot, not beta1.
