How carefully did you test this?

postgres=# \df abc
List of functions
Schema | Name | Result data type | Argument data types
--------+------+------------------+---------------------
public | abc | integer | a integer,b integer
(1 row)

(The argument list should be separated by both a comma and whitespace.)

postgres=# create or replace function xyz(inout a int, inout int)
returns record as 'select (1, 2);' language sql;
CREATE FUNCTION
postgres=# \df xyz
List of functions
Schema | Name | Result data type | Argument data types
--------+------+------------------+----------------------------------
public | xyz | record | INOUT a integer, INOUT integer
(1 row)

(Spurious whitespace for the unnamed INOUT parameter.)

You need to schema-qualify references to builtin functions, to avoid
accidentally using functions of the same name that appear earlier in the
user's search path. (As a general rule, look at the surrounding code
carefully before you modify it.)

It would be nice to be consistent about SQL style, at least within a
single query (e.g. don't separate function arguments with whitespace in
some places but not others).
