Wouldn't bother me -- I'd rather see what's there and make the
"uninteresting" call myself, if that's the only reason for not
showing the I/O functions. It's not like they'd overwhelm the
output.
CREATE DATABASE foo TEMPLATE = template0;
\c foo
SELECT count(*) FROM pg_proc WHERE proargtypes[0] = 'cstring'::regtype;count
------- 63
(1 row)
SELECT count(*) FROM pg_proc;count
------- 1760
(1 row)
