The following bug has been logged online: Bug reference: 3888 Logged by: Marti Raudsepp Email address: [EMAIL PROTECTED] PostgreSQL version: 8.3RC1 Operating system: Linux AMD64 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) To reproduce the bug: # sudo -u postgres postmaster -D $PGDATA -N 8 -B 16 postmaster: the number of buffers (-B) must be at least twice the number of allowed connections (-N) and at least 16 # sudo -u postgres postmaster -D $PGDATA -N 8 -B 21 postmaster: the number of buffers (-B) must be at least twice the number of allowed connections (-N) and at least 16 Specifying -B 22 works as expected. ---------------------------(end of broadcast)--------------------------- TIP 7: You can help support the PostgreSQL project by donating at http://www.postgresql.org/about/donate
