Wow, that was easy. Not sure where I got the impression it was hard
from - probably last looked at it before it was made easy, and didn't
re-check :-)
Updated the pg_stat_get_activity() function to use this.
And yes, I agree that it's probably a very good idea to go over our
other SRFs and fix them all. I can take a look at that eventually, but
for now I think we stick it on the TODO?
