Hi,
I am Suchindra Katageri and am working as a Software Engineer at
Linuxlabs, Atlanta, GA.
I am presently working on developing libraries to make postgresql
run on a cluster. I was wondering if it was possible to force Database
writes to stable storage, without messing up with the postgres code.
e.g. force the PostgreSQL to write to stable storage after an INSERT
command.
I don't see how that would help you very far.
PostgreSQL holds disk buffers in a shared memory cache. And unless you modify that cache, it would not read from the file again if it thinks it knows the content already. How do you intend to remove pages from that shared buffer cache at the time, another cluster member modifies the same logical page?
