Thread: pgsql: localbuf: Introduce StartLocalBufferIO()
localbuf: Introduce StartLocalBufferIO() To initiate IO on a shared buffer we have StartBufferIO(). For temporary table buffers no similar function exists - likely because the code for that currently is very simple due to the lack of concurrency. However, the upcoming AIO support will make it possible to re-encounter a local buffer, while the buffer already is the target of IO. In that case we need to wait for already in-progress IO to complete. This commit makes it easier to add the necessary code, by introducing StartLocalBufferIO().
