There are many code paths in libpq that can trigger an out-of-memory error.
However, this patch makes libpq drop the connection when OOM_result is returned,
which likely covers only a subset of those cases. So I'm not sure dropping
the connection only for OOM_result would meaningfully improve things.

Perhaps it would be more consistent to drop the connection for any
internal libpq error
such as out-of-memory, though that might require invasive code changes and coul
 break existing applications, I'm afraid.
