Dunno where he got that idea.
There are some problems lurking in ADD COLUMN when used on a table with
inheritance children --- the new column is added to the children too, as
it should be, but in an unexpected column position, which causes trouble
for pg_dump (a dump and reload will do the wrong thing). Perhaps what
you heard is a garbled report of that issue.
