Drop those functions and try again.

The PG version I'm using is 9.2.4.it does not work anymore, even using the explicit cast:
It works but after recreating the implicit cast with the function:
CREATE FUNCTION pg_catalog.text(integer) RETURNS text STRICT IMMUTABLE LANGUAGE SQL AS 'SELECT textin(int4out($1));';
CREATE CAST (integer AS text) WITH FUNCTION pg_catalog.text(integer) AS IMPLICIT;

Ah! I missed that.Which version of 9.2 you are working with? I am also at 9.2 and its working fine.Try out usingselect 'teste'||1::int;See if it works or not.On Wed, May 15, 2013 at 3:41 PM, Carlos Henrique Reimer <carlos.reimer@xxxxxxxxxxxxx> wrote:
Actually, as stated in my first note, this is what I've done to fix the select 2 (select trim(1);) but after creating this function/cast the select 1 (select 'teste'||1;) started not working.

Hi,Currently, our application is still using PG 8.2 and we are trying to use 9.2 but there are some problems related with the implicit casts removed on 8.3.Example:
1) select 'teste'||1;
2) select trim(1);Select 1 & 2 does run fine on 8.2 but in 9.2 select 1 is ok and select 2 got an error due the fact implicit cast were removed on PG 8.3:
ERROR: function pg_catalog.btrim(integer) does not exist
LINE 1: select trim(1);

Character: 8Recreated the implicit cast for select 2:
CREATE FUNCTION pg_catalog.text(integer) RETURNS text STRICT IMMUTABLE LANGUAGE SQL AS 'SELECT textin(int4out($1));';
CREATE CAST (integer AS text) WITH FUNCTION pg_catalog.text(integer) AS IMPLICIT;
Now select 2 works fine but select 1 gets an error:
ERROR: operator is not unique: unknown || integer
LINE 1: select 'teste'||1;

Is there a way to make both selects work on PG 9.2 without explicit casts?Thank you in advace!
