Add support for SQL functions referencing to distributed tables

Hi all,

for the last few days I tried some tests with Citus. I noticed that Citus does not support standard SQL functions that query distributed tables (even if they don't take any parameters). I don't really see the overhead that stable inline functions create for Citus that they aren't supported by Citus.

The "best" workaround that I found so far is to use views instead of functions. That works for the functions without parameters but is there any effort to support SQL functions in the future or will this not be implemented?

Thanks in advance:)
