But there is no user2.  I _know_ I am the only user of this database.

So how can User 1 create a race condition by himself?

Or is this something PostgreSQL is doing internally (like vacuum) ?

Do I really just have to keep trying the DROP command N times in a
row, until it decides it wants to work?  That really doesn't seem
right.

Thanks,

Dan
