Try not doing "analyze" --- the most likely cause of the FATAL message is
that the system is trying to copy some damaged column value that
claims to be ridiculously wide.
If nothing else helps, you could manually zero block 3304 of the table,
sacrificing those rows to get back the rest of your data. dd(1) should
work for this, I think, but be sure to shut down the postmaster while
hacking directly on data files. [NB: these are 8K blocks (unless you
changed BLCKSZ) and the file starts with block zero.]
