Thanks for the tip... I had a closer look at the client (did I mention
I was running Perl/DBI as a CGI?) and found that there's some issue in
the way Apache handles stderr prints from a CGI: if the CGI takes a
long time to execute and generates too much output on stderr, Apache
just puts it to sleep. I have all my SQL statements being printed to
the Apache log before execution, and after a while the log buffer or
whatever would just fill up and suspend the process.
Figuring out a workaround (better than the open STDERR,">/tmp/STDERR"
route :) for this, but the program is working as it should now. Or at
least working, trying to make it comply with the requirements :) At
least it's not a PgSQL problem.
