Hi folks,
I tried to create a new type with an array in it. So I took an example
from (the german translation of) "PostgreSQL: Introduction and Concepts"
by Bruce Momjian.
This example says:
create type int4array (
input=array_in,output=array_out,
internallength=variable,element=int4
);
Now, psql complains:
ERROR: TypeCreate: function array_out(int4array) does not exist
I'm using PostgreSQL 7.3.2 (came with SuSE Linux 8.1).
Have things changed, or did I overlook something?
If I ask psql
\df array
array_out (among others) appears in the list of functions.
Myfirst guess is that array_{in,out} is somehow predefined, so that I
have not to define functions by hand - or is this wrong?
Thanks!
Wolfgang
