For a flat file, CREATE INDEX constructs
an index in the same way as an index for a regular table.

For starters, how would you keep the index up-to-date when the flat
file is modified?

One way is to poll the remote source for evidence of such changes
during auto_vacuum or with similar daemon processes.  Another is by
waiting for a signal from an external source such as a NOTIFY.  Which
is more appropriate will again depend on circumstances.

I think that's a good idea.  I'd like to work on it in the future.
