Function access query/queries in Postgres I'm working on a project in which I need to determine which functions a given account has access to run. 

So essentially, if I give this query an ID, can I get a list of functions that ID has access to execute.

Is this possible?

Thanks in advance.
Sounds to me as if you are looking for:

select *
from information_schema.routine_privileges
where grantee = 'arthur';
