Cool, looks interesting! As far as I know EnterpriseDB, Postgres Pro and OracleDB have this functionality. So, seems
likethe stuff is in demand.
How does your version compare to this widely used databases? Is anyone else using backgroud connections? Which syntax
isused by other DBMS'?
Looking into the code it seems like an easy way for PL\pgSQL function to have a client connection. I think this might
workfor other PLs too.
The patch touches translations ( src/backend/po/). I think we typically do not do this in code patches, because this
workis better handled by translators.
