Jasmine,

Please start your own thread rather than replying to some unrelated
thread.

In the particular case above, please also to provide reproducible test
cases including the exact version(s) of PostgreSQL to which they apply
(9.2.4, e.g.) along with output from same so other people can see what
you're talking about and actually help.

Cheers,
David.
