Hello I wrote lot of C VARIADIC functions - some examples are in core - "format" function
Schema | Name | Result data type | Argument data types | Type ------------+-----------+------------------+----------------------+-------- pg_catalog | concat | text | VARIADIC "any" | normal pg_catalog | concat_ws | text | text, VARIADIC "any" | normal pg_catalog | format | text | text, VARIADIC "any" | normal (3 rows) look to http://okbob.blogspot.cz/2010/11/new-version-of-pst-collection-is.html source code (string functions) Code should be same without differences between external and internal functions.
