I think it's my problem - I thought COPY mytable FROM source_file *was* 
something handled by the SQL parser in the backend, i.e. you could use it via 
psql / DBI / jdbc / whatever.

As it turns out, if the source file is an actual file (/tmp/foo.sql) then you 
can, but not if it's "stdin". Presumably, there's some magic going on if you 
use psql/pg_restore (NOTE-should this be mentioned in the docs).

I agree completely with you - a single file containing statements that I can 
run into PG via any convenient connection, not something that works one way 
and not another.
