There's an ETL process that does the following:
- Create a temp table
- COPY into the temp table
- do some transforms on the data
- create a dated table if it doesn't already exist
- fail miserably because the catalog is busted**
**: it normally does something else here, namely inserting a bunch of
rows into the table
The ETL process keeps trying until it succeeds or someone stops it,
so I guess that's why there's so much churn in there for that table.
Kept trying to create it, and ran into the issue. I'd estimate
around 1700 to 1800 dead versions of that table, because it ran for
some time before I noticed and stopped it... this is just a test box
after all, I don't have 8.1 in production yet (thankfully!).
So what do I do now? Kill the database, start over from a dump, and
cross fingers that this doesn't pop up again?
