Hello,
I forgot to add - all those 'out of memory' errors happen when backup db
is trying to create index. Every 'CREATE INDEX' operation is followed by
'out of memory' error.
Thanks!

Hello,
We have a bit of a problem with the daily db backup. At the moment the
backup db size is half of the main db, and we have the following
errors in the log file:
ERROR: out of memory
DETAIL: Failed on request of size 536870912
(There's a bunch of those.)
There were some 'permission denied for language c' errors earlier in
the log, but then the backup continued for a while.
This is the command we're running:
pg_dump -c -h $DB_HOST -U $DB_USER $DB_NAME | PGOPTIONS='-c
maintenance_work_mem=1500MB -c sort_mem=64MB'
psql --quiet -U $DB_DUMP_USER -h $DB_DUMP_HOST $DB_DUMP_NAME;
Both databases (main and backup) are Postgres 8.3.
I'd appreciate any suggestions on how to fix this problem. Also, if
you have a better idea on running a daily backup please let me know.
Thanks!
Marcin
