Folks, experiencing an odd issue. The following on an 8.4 server: select 'foo'::text || 123
Blows up, saying:
ERROR: operator is not unique: text || integer
LINE 1: select 'fo'::text || 123;
^
HINT: Could not choose a best candidate operator. You might need to add explicit type casts.
But on another postgres 8.4 server, it properly returns a concatenated string.
Any tips on how/where I can track down why/where there might be duplicate operators?

psql's "\do ||" might help. Presumably somebody's stuck a user-defined
operator named || into that database ...
