Re: Degradation of performance when upgrade psqlodbc to 09.03.0400

Hi Inoue-san, Heikki-san,

Sorry for continuous disturbing you in this topic.

We found the below SQLSetConnectAttr issue, which was solved in 09.05.

Follow the topic and we solved performance  problem in 09.03.0340 by do SQLSetConnectAttr after create connection.

http://postgresql.nabble.com/issue-SQLDriverConnect-will-clear-existing-connect-attribute-setting-td5832902.html#a5836129

As my confirmation, SQLSetConnectAttr issue is started from 09.03.0100. Which your "Revise MSDTC support" patch is applied.

Does your patch is related to SQLSetConnectAttr issue above? 

If yes, how it does ?

# Sorry but i just want to know the root cause.

Thanks and best regards,
