Re: PQgetvalue failed to return column value for non-text data in binary format

Thank you for your suggestion of COPY API.  I will take a look.  The 
trouble is, I cannot seems to find any example that illustrate any 
non-text data usage.  The PostgreSQL doc is extensive, provided you 
already know the details and serve well during implementation of 
applications.

For beginner, there is no cohesive way to lead me read thru the doc in 
proper sequence.  All tutorial and examples gave me knowledge to do very 
simple stuff.  The extensive documentation only lead to more questions.
