There is a post-7.3.4 bug fix in the 7.3 branch for this mistake:

2003-10-02 18:25 tgl

* src/backend/utils/adt/ruleutils.c (REL7_3_STABLE): When dumping
CREATE INDEX, must show opclass name if the opclass isn't in the
schema search path. Otherwise pg_dump doesn't correctly dump
scenarios where a custom opclass is created in 'public' and then
used by indexes in other schemas.

Since the bug is in the backend and not pg_dump, you can't escape it by
using the 7.4 version of pg_dump against the 7.3 server. You could
recompile the server using the 7.3-branch-head version of ruleutils.c,
though.
