Hello,

Is it possible to find out the (list of) function oids from a function
call?

e.g. select MYFUNC('foo', 1234)

=> someting like

select * from get_function_oids($$MYFUNC('foo', 1234)$$)


best regards,

Marc Mamin

Below approach provides information of the OID of the function::

postgres=# create function myfunc(int) returns int as 'select $1' language sql;

CREATE FUNCTION

postgres=# SELECT 'myfunc(int)'::regprocedure::oid;

oid

-------

24612

(1 row)

postgres=# select 24612::regprocedure;

regprocedure

-----------------

myfunc(integer)
