That's also an interesting approach. An auxiliary table like
transaction integer FK to the transactions table
transaction_nb integer gapless sequence
should do it. A trigger inserting on this auxiliary table would also take
care of everything... If I have an after trigger I believe I wouldn't need
any locking... I have to think about this...
As simple as this might be, I haven't thought about it :-) Thanks for your
suggestion.
