Define a new, more extensible syntax for COPY options.
This is intentionally similar to the recently revised syntax for EXPLAIN
options, ie, (name value, ...). The old syntax is still supported for
backwards compatibility, but we intend that any options added in future
will be provided only in the new syntax.

Can someone add a note to the release checklist to send out infopacks to specific projects about such changes? It would be useful to let ETL vendors know we're extending the syntax options so they can support them by the time we release, rather than 3-6 months after we release. -- Simon Riggs www.2ndQuadrant.com
