But, the problem is more complex for functions because you have to give
the arguments. You can find the list in the pg_proc table but they are
store in a array by oid. So you can resolve the type with the table
pg_type. After, you have to reproduce the correct syntax (with correct
number of orgument, on one execute line...)
Does this help?
SELECT n.nspname || '.' || p.proname ||
'(' || pg_catalog.oidvectortypes(p.proargtypes) || ')'
FROM pg_catalog.pg_proc p
LEFT JOIN pg_catalog.pg_namespace n ON n.oid = p.pronamespace
WHERE p.prorettype <> 'pg_catalog.cstring'::pg_catalog.regtype
AND p.proargtypes[0] <> 'pg_catalog.cstring'::pg_catalog.regtype
AND NOT p.proisagg
AND pg_catalog.pg_function_is_visible(p.oid)
AND p.proname ~ '^format_type$';
?column?

pg_catalog.format_type(oid, integer)
