May be this will help you:


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 nspname != 'pg_catalog'
