Subject: 7.3.1 function problem: ERROR: cache lookup failed for type 0

Hi i had written a C function to easily convert an int4 to its
equivalent 1x1 int4[] array.
It worked fine under 7.1,7.2.
Now under 7.3.1 i get the following message whenever i try to:
dynacom=# select itoar(3126);
ERROR: cache lookup failed for type 0
Surprisingly though when i do something like :
dynacom=# select defid from machdefs where itoar(3126) ~ parents and
level(parents) = 1 order by description,partno;
defid
-------
3137
3127
3130
3129
3133
3136
3135
3128
3131
3132
3134
3138
(12 rows)
it works fine, but then again when i try to EXPLAIN the above (successful)
statement i also get:
dynacom=# EXPLAIN select defid from machdefs where itoar(3126) ~ parents
and
level(parents) = 1 order by description,partno;
ERROR: cache lookup failed for type 0
Any clues of what could be wrong??
The definition of the function is:
CREATE FUNCTION "itoar" (integer) RETURNS integer[] AS
'$libdir/itoar', 'itoar' LANGUAGE 'c' WITH ( iscachable,isstrict );
I also tried without the iscachable option with no luck
(since it seems to complain about *type* 0)
