IncorrectUsage error when batching update statements.

[naushadh]

Issue

• Under high load (upto 512 concurrent requests) in a web app, postgres-wire keeps running into IncorrectUsage: "Expected DataRow message, but got ReadyForQuery" error for a batch of update statements.

• Issue does NOT manifest when the number of concurrent requests is low.

• Related project and workaround I had to apply: TechEmpower/FrameworkBenchmarks@a707305#diff-18e221ebfc6aeb9c7554015904f0c042

Is this expected? Am I doing something wrong?

Thank you for the report! I will investigate this. Also, it will be really helpful if you have a code example that reproduces this issue.
