[Pharo-users] RDBMS Atomic Counter?

Hi, A few weeks ago Sven was asking for a lock-free in-image atomic counter. Today I'm in need of implementing a DB backed (PGSQL) counter for business forms numbering, and maybe there are some toughts you're willing to share :) I can't find any other way than a row lock for each counter, but maybe there is something better (I avoid locks as much as possible). Any thoughts to share here? Regards!
