This is connection pooling for PostgreSQL. It's quite small, installing just one binary, two man pages an an SMF manifest.
Webrev is here: http://cr.opensolaris.org/~bjornmu/pgbouncer-webrev/ One concrete question: One would think the pgbouncer executable would depend on the libpq library (C API) since it suppoprts client using that library, but in fact it doesn't link in that library nor does the source include the header files. So from a purelty technical standpoint, the package does not depend on SUNWpostgr-83-libs and I haven't listed it. But without it, you can't make any sensible use out of it. OTOH, it could also use SUNWpostgr-82-libs. -- Bjorn Munch Database Technology Group, Sun Microsystems Trondheim, Norway
