PostgreSQL version: 8.3RC1

Description: postmaster: misleading error message for illegal -B
values
Details:
When launching postmaster with a small -B (number of buffers) value, it
reports the following error:
"postmaster: the number of buffers (-B) must be at least twice the number of
allowed connections (-N) and at least 16"
However, as of PostgreSQL 8.3, postmaster requires that the number of
buffers is at least (max_connections*2 + 6)
Hmm. The minimum is actually (max_connections + max_autovacuum_workers)
* 2. The default max_autovacuum_workers is 3, which is where that 6
(2*3) comes from.
