Re: Need input on postgres used for phpBB

time.. listed below are some parts of the log.. im wondering why this sql
takes to much time.. they have indexes in place.. or it might be my config?

tcpip_socket = true
max_connections = 260
superuser_reserved_connections = 2

port = 5432
#shared_buffers = 1000
shared_buffers = 40102

effective_cache_size = 4000

max_fsm_pages = 20000
max_fsm_relations = 1000
#fsync = true
#wal_sync_method = fsync

#log_statement = true
#log_duration = true

#syslog = 0                     # range 0-2
#syslog_facility = 'LOCAL0'
#syslog_ident = 'postgres'
