timing psql internal commands - Mailing list pgsql-hackers

I have just noticed that psql's \timing does not apply to internal 
commnds like \copy, which surprised me a bit. Is there any reason why it 
should not apply at least in the case of \copy, which after all does 
real work, as opposed to to the client housekeeping and info functions 
that most psql internal commands perform?

cheers
