Re: [HACKERS] How to debug the wire protocol?

Not sure this solves my problem. I’d like to debug how the server is failing to parse my message, not what it looks like on the wire. I am the one forming the message after all.

My apologies if I missed something.

Hello,

I’ve sent a similar email to the general mailing list but got no reply.

I’m trying to write my own implementation of the wire protocol. I’m stuck at the Parse message where I send it to the server but always get the following error: “Could not parse statement invalid string in message”

Is there a way to see how Postgres parses the message? I’ve set logging to DEBUG5 but the only thing I can see in the logs is, among other things, the message

ERROR:  invalid string in message
FATAL:  invalid frontend message type 63

What is exactly wrong? Is there a way to log the parsing of the message, or should I create my own build of postgres with log statements where I need them?

Many thanks,
