Hi !
Or you can take a dump -c, edit the dump file's appropriate CREATE statement
for your table and column and just read the data back in.

AFAIK you cannot in Postgresql. I suggest you recreate the table with the
correct column datatypes (i.e. rename the table, create the new table and
populate it with values from the original table.) Watch out for triggers and
procedures.
