Bug reference:      2698
Logged by:          Lachhman Dass
Email address:      lachhmand@interrait.com
PostgreSQL version: 8.0
Operating system:   Windows 2000 Professional
Description:        Update table alias not supported
Details:

In the Update statement alias must be supported and the syntax should be

UPDATE [ ONLY ] table alias SET column = { expression | DEFAULT } [, ...]
    [ FROM fromlist ]
    [ WHERE condition ]

this is required when same table is used multiple time in where clause and
you want to restrict the selection.

Thanks,

Lachhman Dass
