This patch still has a few of the problems reported earlier this year.
In [0], it was reported that certain replication commands result in
infinite loops because of faulty error handling. This still happens. I
wrote a test for it, attached here. (I threw in a few more basic tests,
just to have some more coverage that was lacking, and to have a file to
put the new test in.)
In [1], it was reported that server crashes produce duplicate error
messages. This also still happens. I didn't write a test for it, maybe
you have an idea. (Obviously, we could check whether the error message
is literally there twice in the output, but that doesn't seem very
general.) But it's easy to test manually: just have psql connect, shut
down the server, then run a query.
Additionally, I looked into the Coverity issue reported in [2]. That
one is fixed, but I figured it would be good to be able to check your
patches with a static analyzer in a similar way. I don't have the
ability to run Coverity locally, so I looked at scan-build and fixed a
few minor warnings, also attached as a patch. Your current patch
appears to be okay in that regard.
