Transactional DDL

["Harpreet Dhaliwal" <harpreet.dhaliwal01@xxxxxxxxx>]

Hi,
I read a few lines about SP compilation in postgres

http://searchoracle.techtarget.com/originalContent/0,289142,sid41_gci1179016,00.html

 

1. stored procedure compilation is transactional. 

"You can recompile a stored procedure on a live system, and only transactions starting after that compilation will see the changes," he said. "Transactions in process can complete with the old version. Oracle just blocks on the busy procedure."

 

Is this what the Transactional DDL feature of postgresql talks about ?

Thanks
