Обсуждение: Can I make direct calls to PostgreSQL server?

I am new to this list, forgive me if I do something wrong.

I am writing an application in C++ for Linux to post data to a PostgreSQL
server.
Can I make direct calls to PostgreSQL server? I have a lot of data to post to
the local PostgreSQL server. I am wondering if I can connect directly to it
to post data so I can by pass the extra layers of
command -> SQL text string -> port -> SQL interpreter -> internal DB command
I would like to go
command -> lib function call  -> internal DB command

All I can find is examples of how to make long text strings of SQL commands
then pass them to a local port then on into the server. Is this the only way?

You could issue a COPY FROM STDIN command and then send your data in
COPY format.  This assumes that you are setting all the columns
explicitly (COPY doesn't supply defaults for omitted columns, the way
INSERT can) but it saves an awful lot of overhead.
