You're getting good results with 7.4/8.0/8.1, perchance???

Hmm...

There's history of a threading issue on Solaris...  Some versions of the
client library (e.g. - libpq) required patching, and my first question
is, are you certain you compiled PostgreSQL 7.3.8 with the option
"--enable-thread-safety"???

Without that option, and possibly without a patch akin to
<http://developer.postgresql.org/~wieck/slony1/download/threadsafe-libpq-742.diff.gz>,
you'll find that slon will fall over...
