Alvaro Herrera napsal(a):
This code would be run-time or compile-time configurable. I'm not
absolutely sure which yet; the problem with run-time is what to do if
the user restarts the server with the setting flipped. It would have
almost no impact on users who don't enable it.
I prefer runtime configuration. Solaris has two filesystems UFS, ZFS.
ZFS offers strong error detection and a another CRC is overhead. You
need mechanism how to enable this feature on UFS and disable on ZFS. I
suggest to have it as tablespace property and for default tablespace you
can setup it in initdb phase.
