Try to select all content to temporary table, then drop old table, create
new with unneeded column(s) removed, and them reselect all data back.

Also, don't forget to re-create indexes, rules, views and other
table-related things as they are reference table by its (internal to
Postgres) ID. Also don't forget to create needed permissions.

For large tables, dumping, editing schema & data with simple script and
then recreating database may be simpler solution...
