Bizarre. I looked through the recent sslmode patch, and while I found
some things I didn't like, none of them explain this. Could you perhaps
get a trace of the server-to-client interaction? Either strace'ing psql
or watching the IP traffic with a packet sniffer should do --- but make
sure you get the full contents of each packet sent and received.


Hi Tom,

the attached file is a tcpdump of a connect attempt.

Andreas
