5 extra processes would be exactly what I'd expect in an 8.3
installation. I don't remember the magic incantation to get Solaris'
ps to show you useful descriptions, but on most platforms what you'd
see is something like this:
postgres 8522 1 0 13:37:37 pts/2 0:00 postmaster
postgres 8525 8522 0 13:37:37 ? 0:00 postgres: writer process
postgres 8526 8522 0 13:37:37 ? 0:00 postgres: wal writer process
postgres 8527 8522 0 13:37:37 ? 0:00 postgres: autovacuum launcher
process
postgres 8528 8522 0 13:37:37 ? 0:00 postgres: stats collector
process

You can't kill them without taking down the database. I will bet large
odds that they aren't "eating memory", either --- you have probably got
Postgres' shared memory area set to about 1GB, and you are looking at
the output of tools that report all of that as belonging to each process
that's connected to the shared memory segment.
