StartupDecodingContext() initializes ctx->reader->private_data with ctx, and
it even does so twice. I couldn't find a place in the code where the
(LogicalDecodingContext *) pointer is retrieved from the reader, and a simple
test of logical replication works if the patch below is applied. Thus I assume
that assignment is a thinko, isn't it?
