David, Daniele: thank you for replying.
David: the search routine works correctly in one environment, so I don't 
think raw SQL is the answer
Daniele: What would be the 'search_path'? As I said, 'search.sql' is in 
the same directory as other Python modules used by the application, and 
no path variable was set when I first copied  the code from Stack 
Exchange and tested it.
I can find no references to path/environment in Postgresql's 
documentation of pl/pgsql.
