This version is pretty old -- if you must use 7.2, then consider
upgrading to 7.2.7. Better yet, try a newer release like 8.0.1.

Please show the exact statement you executed and describe how it
didn't work. If you got an error message, then please copy and
paste it verbatim. Without more information we can't tell you
what's wrong.

TIP 5: Have you checked our extensive FAQ?

As Tom observed, you might be reading documentation for a later
version and are trying to do something that 7.2 doesn't support.
Here's a link to the 7.2 documentation:

http://www.postgresql.org/docs/7.2/i...ive/index.html
http://www.postgresql.org/docs/7.2/i...ltertable.html

The ability to change a column's type with ALTER TABLE was added
in 8.0 (even so, the syntax you show is incorrect). Since you're
using 7.2, you'll have to use the method mentioned in the FAQ:

http://www.postgresql.org/docs/faqs.FAQ.html#4.3

However, you won't be able to cast the integer column directly to
date, so you'll have to use an expression that performs the desired
conversion.
