[DOCS] number of semaphores and semaphore sets

2011-03-21 Thread Anton Yuzhaninov

This page:
http://www.postgresql.org/docs/9.0/interactive/kernel-resources.html

has formula:
ceil((max_connections + autovacuum_max_workers) / 16)

for number of semaphore sets (identifiers).

It seems to be wrong (outdated).

Correct formula seems to be

ceil((max_connections + autovacuum_max_workers + 4) / 16)

Semaphore sets created in src/backend/storage/lmgr/proc.c:
1. MaxConnections
2. autovacuum_max_workers + 1
3. NUM_AUXILIARY_PROCS (currently 3)

To the person responsible.

Before you create the next update to the PDF files, please do a review to 
correct all the prototypes that have their text being truncated at the right 
margin.  The respecting of margins means I may be able to use my e-book to read 
the pdf. I do a lot of commuting and benefit from off-line reading.

How do you want a patch. I will give you page and line from the existing PDF, 
if that is what you would like.
