src/port/gettimeofday.c extends things on Windows, and we could consider to just drop the timing portion for simplicity (except Windows I am not seeing any platform missing timersub). But that's just a point of detail. Or we could just drop those tests from the final patch, and re-implement them after having some psql-level subcommands.

I would think that something like "cannot process COPY results during a batch processing" would be cleaner. Isn't some more error handling necessary in GetCopyStart()? > Attached the latest code and test patches. For me the test is still broken: ok 1 - testlibpqbatch disallowed_in_batch ok 2 - testlibpqbatch simple_batch ok 3 - testlibpqbatch multi_batch ok 4 - testlibpqbatch batch_abort ok 5 - testlibpqbatch timings not ok 6 - testlibpqbatch copyfailure Still broken here. I can see that this patch is having enough safeguards in PQbatchBegin() and PQsendQueryStart(), but this issue is really pointing out at something... -- Michael -- Sent via pgsql-hackers mailing list (firstname.lastname@example.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
