This isn’t a high-priority question. I’m developing a hobby OS and I’m looking into
file systems. I’ve thought about writing my own, and that appeals, but I’m
also very interested in the database-as-a-filesystem paradigm. It would be
nice to not have to write all of the stuff that goes into the DBMS (e.g. parsers,
query schedulers, etc) myself. So I was wondering what sort of filesystem requirements
Postgre has. For example, could I write a simple interface layer that just
requests blocks from the physical device and translate those into byte sets, or
does the DB actually require multiple files mapped by a larger file system that
maintains names, etc. I guess my real question is how much file system support is
really required by the DBMS’s disk routines. Please reply to -={C}=- |
