I certainly don't propose changing the PostgreSQL error number or the
content of what is logged. Just the SQLSTATE. How would that make
what you suggest harder? It would certainly allow applications and
frameworks which are SQLSTATE-aware to automatically recover from
these until the rewrite is complete, which can hardly be considered a
bad thing.
