[ SOLVED ] Re: possible data loss.

~~~~~~~~~~~~~~~~~~~~~~~
There was no data loss.
~~~~~~~~~~~~~~~~~~~~~~~

This message was posted during the disturbance
period in our mailing lists. hence could not
update on this .

In fact i was under the impression that it would
have never reached the lists.


My false assertion was based on disappearance of the
records from the user interface of a certain application
which did not bother to display errors to browser from
the database. It was only when i peeked into postgres
log that i realized whats going on.


Actaully i had added a txtidx feild in certain table from
which distinct * was being performed since txtidx type did
not have < or > operators it was rasing errors.
later i removed that column (by some means) and the problem
got corrected.

I got the shock of my life as i really did not have
backups but now i started. my be lord was kind enough
to make me realize timely on the lack of back ups.
