I'm wondering about the relevance of this pre-7.4-final bug fix:
2003-10-19 17:36 tgl
* src/interfaces/libpq/: fe-exec.c, fe-misc.c: Adjust libpq to
avoid deadlock when both client and server want to send data, and
both have filled the transmission buffers. One scenario where this
can happen was illustrated here:
http://archives.postgresql.org/pgsql-hackers/2003-04/msg00979.php
Supposing that a 7.4-beta libpq were in use, and for some reason the
server tries to send a large reply message before it's absorbed all
of the command, we could see a hangup like this. It'd be useful to
see an strace of the server process in parallel with the client.
