The following bug has been logged on the website: Bug reference: 7529 Logged by: Lego Haryanto Email address: legoharya...@gmail.com PostgreSQL version: 9.0.5 Operating system: Any Description:
I understand that current transaction behavior in PostgreSQL is to throw away the whole transaction away (rollback) if there's at least one error within the transaction. I believe on certain application of data replication, say, migration from other database source, ... this will be pretty cumbersome to support in PostgreSQL even though users have some conflict resolution strategy in mind. On the following scenario, imagine this transaction is coming from a source of different DB, migrating into a PostgreSQL target. BEGIN INSERT #1... (success) INSERT #2... (success) INSERT #3... (error or conflict/collision) INSERT #4... (success) COMMIT; Current behavior of PostgreSQL is that the INSERT #4 command is ignored because of the error on INSERT #3 (subsequent commands are ignored). And the COMMIT command is accepted as ROLLBACK, which we can argue it's misleading because user does an explicit COMMIT, but the actual action is a rollback. Can we actually support honoring the successful DMLs above, and do the actual COMMIT that is inserting #1, #2, and #4 in above example? -- Sent via pgsql-bugs mailing list (pgsql-bugs@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-bugs
