Its not a bug - automatic casting was removed in 8.3. You should cast( a as text)||cast(b ... = cast(123456 as text). Other option is to define your own operators which is to be used only in case you can not fix clients of your database...

hi,all for example tableA create table tableA ( id serial, a integer, b integer, c integer ); insert into tableA (a,b,c) values (12,34,56);
then, select id from tableA where (a||b||c)=123456; in postgresql version 8.2.11,it works. but in postgresql version 8.3.6,the error as bellow: ERROR: operator does not exist: integer || integer LINE 1: select id from tableA where (a||b||c)=123456; ^ HINT: No operator matches the given name and argument type(s). You might need to add explicit type casts.
is it a bug in 8.2.11 or I install 8.3.6 not completely?
