"have an fsync that doesn't really flush to disk. OS X requires fcntl(F_FULLFSYNC) to flush to disk" I remember highlighting this problem to the Firebird db developers maybe 13 years ago. AFAIR they were open to the problem I'd pointed out and went about fixing it on other platforms so that the db behaved everywhere as it did on OS X. I'm probably in the bottom 5% of IT professionals on this site. I'm rather amazed to find out that so late in the day Postgres has come round to fixing this. I haven't used Firebird in years and can't find a link to the discussion (could have been via email).
