ah, of course. the exclusive lock was preventing tty1 to read "test", and when the lock was gone, so was the table. I get it. Thanks a lot.
But, what about the "ERROR: tuple concurrently updated" ? (in TTY3) What should have happened, i guess, is "ERROR: table "test" does not exist, upon " drop table test; --4. ..." Which tuple was concurrently updated? A pg_catalog entry that administers the table?
