People,
I am converting C++ code to Postgres.
Need help on how to deal with mysql_fetch_row, mysql_store_result
functions in Postgres? There should be some C/C++ code available for
these things, I hope.
Thanks,
Alex.

The libpq API is slightly thicker than mysql, which essentially
returns char ** for MYSQL_ROW.

With pg, you have a lot of flexibility with how you send queries,
parameterized, asynchronous, prepared, etc. For starters though you
want to look at PQexec which maps to (iirc) mysql_real_query, more or
less.

libpq has very nice handling of binary data -- the protocol has
ability to send and receive blobs (and other things) without escaping
-- which is nice.
