Without a reproducible test case, it's tough to see how anyone's going
to be able to fix any bug that may be lurking here. When you use
vague phrases like "when didn't close the application, weird things
occurred", it's kind of hard to figure out what exactly you did. If
you come up with a specific sequence of steps involving simple tools
like pg_dump and psql that produces a result you think is wrong,
someone here can probably (a) tell you whether the behavior is
intended, and (b) if not, fix it.
