    Subjectfsync vs fdatasync on Linux
    Date
    Hello,

    as fas as I can see from fdatasync man page, and from the latest kernel
    sources (2.4.1ac3, fs/buffer.c), they are equivalent.

    Using of fdatasync in database can gain significant gain on systems which
    supports it (on HP it gains up to 25% with pg_bench on PostgreSQL 7.1b5).

    Are there any plans to implement this correctly? And due to what problems it
    was not implemented yet?
