Re: pthreads issue when compiling 7.4.8 on AIX 5.3

Wow...<light dawning on marble head>....so this means..if I want to
do replication, I'll need to rebuild PG with --enable-thread-safety?

that's unpleasant news, since, IIRC, it didn't like it at all, first
time through.

<sigh>

Thanks for heads up.

Slony uses a threaded libpq, which is what --enable-thread-safety does.
