Perhaps the "Per-table granularity" line in the matrix (Table 25-1)
might be better written as:
"Synchronization Granularity"
Columns 1-3 and 5 could say "Entire Cluster". Column 4 might say
"Selected tables (Slony)", and I'm not sure off-hand what granularity #6
(Bucardo) is capable of. Column #7 might just say "Varies".
For someone not familiar with what exactly WAL files are, it's not clear
that solution #3 is an all-or-nothing approaches at the cluster level.
Now that I've refreshed my memory on how WAL files work (and at what
level in the pgsql cluster), I understand why #3 works the way it does.
