True. I was first thinking of doing this only if we know we're in
a DML query, ie *first* word on the line is
WITH/SELECT/INSERT/UPDATE/DELETE. However, in the current
implementation that is not terribly workable because we are only looking
at the current line of text, not the whole input buffer; so making such
a restriction would disable completion after the first line of a multi-
line command.

Yup. At the very least it would be good if it had access to the entire
current command, so that we could sanity-check on the basis of the first
word.
