Function quote_literal broken in CATALOG_VERSION_NO 200707251

Just FYI:

I took the latest snapshot CATALOG_VERSION_NO 200707251 and function
quote_literal throws an error:

# select quote_literal(1);
2007-08-20 18:50:17 PDT ERROR: function quote_literal(integer) does not
exist at character 8
2007-08-20 18:50:17 PDT HINT: No function matches the given name and
argument types. You might need to add explicit type casts.
2007-08-20 18:50:17 PDT STATEMENT: select quote_literal(1);
ERROR: function quote_literal(integer) does not exist
LINE 1: select quote_literal(1);

I went back to an older snapshot CATALOG_VERSION_NO 200705211 and it
works with the same SunStudio compiler and options:

postgres=# select quote_literal(1);
quote_literal
---------------
'1'
(1 row)
