What reported that? The PostgreSQL server doesn't report such
things directly, and I don't know pgadmin, so I don't know about
that tool. I wrote the recursive query on this page:
http://wiki.postgresql.org/wiki/Lock_dependency_information
So if that reported anything incorrecly, please let me know so I can
fix it.
By the way, the example with the three connections would have been
better had I suggested a BEGIN TRANSACTION ISOLATION LEVEL
REPEATABLE READ; on the third connection. With that, even if one or
both of the transactions on the other connections committed, the
third transaction's count should remain unchanged.
