-----------------------------------------------
I have 2 databases. "test" and "working"
There r 39 tables in "test", very less data in them.
There r 40 tables in "working" and there is some data, not too much. And
there are referential integrety ocnstraints between the data.

When i do a "pg_dump test" it works fine.
But When i do a "pg_dump working" I get "Segmentation fault (core dumped)"

If anybody wants, i can send the core file. Any help will be highly
appreciated.
