Hello!
Is there any example could help in usage
of COPY BINARY since I am a little bit discouraged by this part of PG manual
==
To determine the appropriate binary format for the actual tuple data you should consult the PostgreSQL source, in particular the *send and *recv functions for each column's data type (typically these functions are found in the src/backend/utils/adt/ directory of the source distribution).
==
I use libpq.
And question number 0: how big perfomance difference between TEXT and BINARY formats ?
Thanks.
