Add function resource

[dump247]

The use case for this resource is setting up datadog agent access. It requires defining a datadog.explain_statement function that the dd agent expects to exist. I can setup everything in terraform except for the required function.

@cyrilgdn Would you be able to take a look at this?

@cyrilgdn Any feedback for this change?

If it helps, I would be happy to accept longer term responsibility for this resource. I don't know how that would work, but I can tackle bugs and such.

@dump247 I'll have a look as soon as I can, it could take a few days though, sorry for that.

[dump247]

No worries. Thank you for taking a look. Let me know if there is anything I can do to facilitate the review.

@cyrilgdn Any updates?

Just a tiny comment about unnecessary use of transaction that can simplify the code, otherwise it's look good 👍
Many thanks for your work on this and sorry again for the response delay.

@dump247 Thanks a lot for your work on that 👍

FYI, this has just been released in v1.16.0

Hi @cyrilgdn ,
Thank you for this new postgresql_function ressource !

Would it be possible to add support for the "database" parameter for this ressource as well ?
Right now, it seems like there is no way to override the provider's database.

Thank you
