Drat! I'm wrong again. I thought for sure there wouldn't be a
wraparound problem.
So does this affect the entire database server, or just this table?
Is best way to
proceed to immediately ditch this db and promote one of my slaves to
a master? I'm just
concerned about the data integrity. Note that I don't use OID for
anything really, so I'm
hoping I'll be safe.
Thanks again, Tom.

so I have to conclude that you've got a wraparound problem. What
is the
current XID counter? (pg_controldata will give you that, along with a
lot of other junk.) It might also be interesting to take a look at
"ls -l $PGDATA/pg_clog"; the mod times on the files in there would
give
us an idea how fast XIDs are being consumed.
