Hi Nafiseh,
Based on this document
http://techdocs.postgresql.org/techdocs/updatingcolumns.php, this
feature has not been implemented yet in postgres. I think you can dump
this column to a file, or a dummy table, and drop it. Then, you can add
it again with the correct type and load your data.
hi.

table that build in past ?
