Re: Questions regarding SET option.

[Jignesh Shah <jignesh.shah1980@xxxxxxxxx>]

Thanks a ton Laurenz and Pavel for your responses but I really didn't follow you. I am not master in PostGreSQL yet. Could you please give me some example? 

Basically, I want to know how many such SET options I should reset before executing my function and at the end it should also be restored to original settings.

It would be really helpful if you could elaborate your response.

Thanks guys.

You can use the SET clause of CREATE FUNCTION which does exactly
what you want.
