Hello,
I use hot standby replication mode.
When I try to recreate big sized materialised views, about 3G size, the replication breaks and I have to resync it.
Is there any way to avoid it?
My master server settings
shared_buffers = 30GB
work_mem = 3146kB
maintenance_work_mem = 2GB
dynamic_shared_memory_type = posix # the default is the first option
wal_level = hot_standby
wal_buffers = 16MB
checkpoint_segments = 128
checkpoint_completion_target = 0.9
max_wal_senders = 128
wal_keep_segments = 8
effective_cache_size = 90GB
default_statistics_target = 100
logging_collector = on # Enable capturing of stderr and csvlog
log_directory = '/var/log/postgresql' # directory where log files are written,
log_filename = 'postgresql-%Y-%m-%d.log' # log file name pattern,
log_rotation_age = 1d # Automatic rotation of logfiles will
log_min_duration_statement = 3000 # -1 is disabled, 0 logs all statements
log_line_prefix = '%t ' # special values:
log_timezone = 'localtime'
stats_temp_directory = '/var/run/postgresql/9.4-main.pg_stat_tmp'
autovacuum = on # Enable autovacuum subprocess? 'on'
log_autovacuum_min_duration = -1 # -1 disables, 0 logs all actions and
autovacuum_max_workers = 3 # max number of autovacuum subprocesses
autovacuum_naptime = 15min # time between autovacuum runs
autovacuum_vacuum_threshold = 50 # min number of row updates before
autovacuum_analyze_threshold = 50 # min number of row updates before
Regards,
Dimitris
