I was hoping someone could shed some light on the
following problem:
After increasing the buffer size of the postmaster
using the -B option to 256, we suffered a backend
crash which caused the backend to crash so hard,
no further connections could be made.
I rebooted the server (an intranet Web server-based
application), and attempted to reaccess the database
using the application. The application had problems
querying one of the tables, where the query would
simply suspend forever. After rebooting again, I
decided to run a VACUUM ANALYZE manually (We run it
via cron every night), and received the following
message:
NOTICE: AbortTransaction and not in in-progress state
NOTICE: AbortTransaction and not in in-progress state
After perusing Usenet for similar problems, someone
had reported that they experienced the problem when
they increased their buffer size over 128K. The
Usenet article was pre-6.4 (9/14/98). I decreased the
buffer to 128, restarted the postmaster (I actually
rebooted), and reran VACUUM ANALYZE without problems.
Is it safe to increase the buffer size above 128K?
I did this because one of the queries (a 6-way join)
caused the backend to report an error telling me
to increase the buffer size.
Thanks for any info,
