Since ShMem can't be split across different PgSQL instances on the same 
machine (even with Jails), hard PgSQL separation is required (thus domains 
in network auth mechanisms).

For Slony, there's a 1:1 set of processes per authentication credentials 
(db connect string), so on systems where a single PgSQL instance exists 
but credentials are split up to serve multiple clients with autonomous 
table/view/replication sets, multiple instances (PID files, configs, db 
connect strings, etc.) must run and coexist without overlapping.

Thus, unambiguously stolen from the Apache apache22.sh.in.  Uses all the 
rc.subr(8) hooks.

This will need %%PREFIX%% substitution to make its way back into the ports 
tree.

Also I do some more aggressive sanity checking on configs/variables than 
the Apache version.  May be slightly redundant, but we're talking about 
DBA work here. >:}
