In general it's up to you to make sure that the remote table definition matches
the local one. You can use IMPORT FOREIGN SCHEMA (1) to automate this process,
but you will still have to make sure that any subsequent modification on the
remote table (added/removed column, changed datatype...) is also done on the
local foreign table.

This isn't really related to the previous discussion so it's quite ok, although
it's usually a good practice to trim the unwanted parts of the previous
message (in this case the whole previous message).
