Instead of an interpretation of what's happening, could we see the exact
commands you are issuing and the exact error messages you get?
Also, what other backends are connected to that DB, and what are they doing?
If there is a dangling lock someplace, restarting the postmaster ought
to get rid of it, but that will destroy all the evidence --- so I'd
recommend not doing that until we understand what's happening.
