I don't understand how to do this. I've read the manual at
http://www.postgresql.org/docs/7.4/interactive/sql-reindex.html
It mentions that "standalone server must be used to repair" system catalogs,
but doesn't give any special instructions to do so.

I tried REINDEX for various databases and it says it's doing something,
but when I try to list the databases or pg_dumpall it says it is empty.
However, as I mentioned earlier if I run a specific SELECT on any of my
user tables I see the data.

$ postgres -P -D /usr/local/databases/pgsql/data template0
backend> reindex database template0;
