Hi!

What would be the proposed way, to set up a behaviour like this:

1. Read one row into memory (select * from table)
2. manipulate it in memory (takes a long time, so I don't want to have
in within transaction)
3. if row has the same version number as before: write new data back to
table (update table set ...)
else croak

I guess it can be done with a special setup of transaction isolation
level and pessimistic locking.

Currently I often run into deadlock errors.

I'm pretty sure I'm just too dumb to find out?

Can anyone give me a hint?

Regards, Boris
