Create the functions:
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;
CREATE CAST (integer AS text) WITH FUNCTION pg_catalog.text(integer) AS IMPLICIT;
It'll work.

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!
