operator is not unique: smallint[] @> smallint[] You might need to add explicit type casts (!)

[Marc Mamin <M.Mamin@xxxxxxxxxxxx>]

Hello,

(Postgres 9.3.4)

I don't know how to apply the tip provided along with the error message :-)

This issue may be related to the usage of intarray that seems to have added an
_int4 @> _int4 operator to public:


set search_path=public;

select '{1}'::int2[] @> '{1}'::int2[]
operator is not unique: smallint[] @> smallint[]

but it works with int4[] and int8[]


The error does not ocure when ignoring public:

set search_path=user;

select '{1}'::int2[] @> '{1}'::int2[]
true
