I'm confused. I have a bytea column that should be binary format (right?), yet PQfformat() says it is NOT binary (I did
aninsert as such: INSERT INTO tablename values (..., '\\001\\002\\000'); ). I also tried: INSERT INTO tablename values
(...,'\\001\\002\\000'::bytea); .
Furthermore, my client code receives via PQgetvalue() a backslashed octet string which needs to be converted back into
binarydata via PQunescapeBytea() to get the binary contents, yet the documentation under PQunescapeBytea() (section
27.3.2)says its not needed when receiving binary data (implying there is a way to get binary data). How do I
get/requestbinary data instead of text strings. My client code is connecting via TCP/IP if that makes a difference. I
alsonoted in the documentation some sample client code that converted an int4 column to binary via: ntohl() also
implyingit was in binary format to begin with.
What's the secret? I would love to deal directly with binary data to avoid repetitious conversions to/from strings.
Thanks in advance for any advise!
