I've written an approximation of "commit triggers" for PostgreSQL using CONSTRAINT TRIGGERs (as users have often been told to do who want this feature). Semantics (and a warning) are included in commentary in the source: https://github.com/twosigma/postgresql-contrib/ https://github.com/twosigma/postgresql-contrib/blob/master/commit_trigger.sql https://raw.githubusercontent.com/twosigma/postgresql-contrib/master/commit_trigger.sql I suspect a number of users here may find this useful. I've also posted separately to pgsql-hackers to see if we can get agreement that commit triggers are a reasonable and desirable feature.
