This is what I waited for, finally another opinion. I will delete this
from the grammar.
What about the other question about the 0 vs 1 distinction?
Without the second patch, 0 drives the cursor with the old
ECPGdo() code. All other values drive the cursor via the new
ECPGopen() et.al. Should we keep this behaviour? In this case
the 0 vs 1 distinction is not needed in add_cursor() as the 0
value doesn't even reach ECPGopen().
But if we consider including the second patch as well, should we
keep the "NO READAHEAD" option in the grammar and in cursor.c?
After solving the problem with WHERE CURRENT OF, this and
the 0-vs-1 distinction starts to feel pointless.
And what about the override via the environment variable?
Should it work only upwards?
