Perhaps for the typical use-case this is sufficient though.
I'm open to better ideas, comments, objections...
If the use case is people running MySQL dumps, then there will be
millions of values-targetlists in MySQL dumps.
Yeah. The fabricated select hack does feel wrong to me. Taking a quick
2 minute look at the grammar it looks like a better bet would be to make
InsertStmt.targetList a list of lists of values rather than just a list
of values. Of course, that would make the changes more invasive. Even
with that we'd still be reading the whole thing into memory ... is there
a sane way to cache the inline data before statement execution?
I guess we can just say that for true bulk load our supported mechanism
is still just COPY, but it would be a pity to restrict a feature that is
in the standard that way.
