Обсуждение: failed index creation: ERROR: index_formtuple

Hello -

I've had a nonclustered index on a column of type "character varying(11)"
for many years.
I dropped it and went to recreate the exact same index, but it fails every
time.

create index edata_idx1 on edata (mbrnum);
mbrnum is character varying(11)
number of rows in table: 1326205
postgresql 7.3.4 on Linux 2.4.9-31

ERROR:  index_formtuple: data takes 28640 bytes, max is 8191

Any ideas?  Any work arounds?

Sincerely,

Nate Teller

Ugh :-(.  It's certainly not possible for a valid varchar(11) value to
need 28k bytes.  You have evidently got some corrupted data in your
table.  I'd suggest scanning the table for clearly-bogus rows and
getting rid of them.  Another approach is to pg_dump the table and
try to reload it.
