Yes, that should work.

Which version are you using? I get this:
postgres@feivel:/home/postgres/pgsql/src/interfaces/ecpg$ ./a
[21964]: ECPGdebug: set to 1
[21964]: ECPGconnect: opening database mm on <DEFAULT> port <DEFAULT>
[21964]: ECPGexecute line 16: QUERY: select n from t on connection mm
[21964]: ECPGexecute line 16: Correctly got 0 tuples with 1 fields
[21964]: raising sqlcode 100 in line 16, 'No data found in line 16.'.
no data found
[21964]: ecpg_finish: Connection mm closed.
Looks okay, doesn't it?
