triggers using the correct schema ..

Hi,

We have lots of schemas .. one of which is public. They all have the
same set of tables and some of these have triggers. However when a
trigger is fired in a schema it works on tables in the public schema
instead of the "current" schema. We can put a statement similar to set
search_path = "schema_x"; in the front of each trigger ... but we use a
script to generate these schemas so means doing a search and replace for
each creation that we do. Is there a CURRENT SCHEMA type of command such
that we could do .... Set search_path = CURRENT SCHEMA ?????

Thanks
