Re: Could not create a table named "USER" under postgreSQL

Are you aware that there is NO zero year? The common era starts with
the year 1 AD. There is also no zero month, and there is no zero day.
All three parts of your date are hence invalid. E.g. the date
0000-00-00 does not exist, and neither does 0001-00-00 or 0000-01-00
etc. If you are determined to insert bad data into these fields, you
could make them character. Or you could choose a valid date as the
default.

Remarkably clever to repair all those defects to something remotely
sensible. Whoever wrote that script, I give an 'A+'.
