I'm currently doing a small writeup of a bug fix in our framework which involves savepoints in PostgreSQL (JDBC). However, I have a hard time locating the documentation regarding this. I mean, from what I can extract from various sources, PostgreSQL requires to use savepoints if one wants to continue a transaction after a failed statement, but I can't find where in the documentation that is stated and documented. Can somebody point me to the correct location where this is documented and maybe even explained why that is the case?
