Hi.
We're planning to move away from Blobs (stored as OID) and use files with
path/URI stored in DB. For this to be reliable we're planning to do rename()
(which is atomic) in a constraint trigger, which triggers on commit. The plan
is to write stuff to a file (with at tmp-filename) in the application and to
pass the absolute file-name down to the DB so the trigger can rename it ON
COMMIT. This way we can use a naming-convention to figure out what files are OK
and which are not (which can be deleted due to rolled back transactions).
I have found this extension: https://github.com/csimsek/pgsql-fio/
but it doesn't seem to support renaming.
Any advice on how to proceed?
Thanks.
