Greetings,
Starting PostgreSQL 8.3.0 with the default options used by Gentoo Linux
(-N 40 -B 80) causes it to bail with an error message.
"the number of buffers (-B) must be at least twice the number of allowed
connections (-N) and at least 16"
The problem is that NBuffers is actually "max autovacuum connections" +
NBuffers.
My attached patch fixes this by adding "max autovacuum connections" * 2
to NBuffers before the check.
Best regards,
Andreas Kling
