Hi,
Our company is planning to move to postreSQL. We were initially using sybase where upsert functionality was available using "insert on existing update" clause. I know there multiple ways to fix this using RULE or separate function in postgresql. But I would like to know which version of postgresql has support for upsert planned using an official syntax. I have postgresql 9.2 which does not have this feature, if its planned in near future, I would rather wait to migrate to PostgreSQL.
Thanks,
Sajeev
