Evidently Ian is just interested in a parser that could be used by
Oracle-compatible applications, which'd not be invoking such operations
anyway. Maintenance scripts would have to use the regular PG parser.
That doesn't seem unreasonable.
Based on his further explanation, it seems that tracking grammar changes
wouldn't be an issue, but tracking parsetree changes definitely would
be. I'm also still concerned about whether this can be done within the
parse step (no database access).
