### Steps to reproduce: 1. Start [greeter_server](https://github.com/grpc/grpc-go/tree/master/examples) ``` $ ~/go/bin/greeter_server ... ``` 2. Copy [helloworld.proto](https://github.com/grpc/grpc-go/blob/master/examples/helloworld/helloworld/helloworld.proto) to proto/helloworld/helloworld.proto Copy [any.proto](https://github.com/protocolbuffers/protobuf/blob/master/src/google/protobuf/any.proto) to proto/google/protobuf/any.proto 3. Edit helloworld.proto and add a filed of type...

This can be demonstrated with the grpc-go [sample code](https://github.com/grpc/grpc-go/tree/master/examples/features/errors). 1. Start the sample server ``` $ go run ./server ``` 2. Copy [helloworld.proto](https://github.com/grpc/grpc-go/blob/master/examples/helloworld/helloworld/helloworld.proto) to proto/helloworld/helloworld.proto 3. Start grpc-dump ``` $...

Run the [metadata example](https://github.com/grpc/grpc-go/tree/master/examples/features/metadata) through grpc-dump and observe that client hangs. 1. Start the server ``` $ go run ./server server listening at [::]:50051 ``` 2. Start grpc-dump ``` $...

This race conditioin manifested itself as occasional hangs of dbms_pipe tests. Also, drop obsolete null check of ShmemInitStruct's return value.

queryid is cleared too early with nested queries

Here is a demo using two sessions distinguished with indentation: ``` postgres=# select * from pg_wait_sampling_current where pid = 65936; pid | event_type | event | queryid -------+------------+------------+--------- 65936 |...

Synchronization with collector may be lost if backend is terminated

Consider the following scenario: 1. Session 1 requests history. 2. Session 1 is terminated while wating for collector. 3. Session 2 requests profile. 4. Collector sends history requested by session...

They probably should be in a header. On Linux: ``` $ objdump -d pg_wait_sampling.so | grep -i 'call.*compat' 3e4c: e8 8f f7 ff ff callq 35e0 47b4: e8 97 ef...
