Hello,
I am trying to set up streaming replication with barman, going down the
tutorial.
When I run/ I get:
$barman receive-wal --create-slot pg
ERROR: Cannot connect to server 'pg'
##############################################################
Both servers Ubuntu 18.04, Postgresql 12.1
These are the configurations I have set up so far:
The Main Postgres Server: ###############################
$nano /etc/postgresql/12/main/postgresql.conf
--------------------------------------------------
....
listening_addresses = '*'
wal_level = hot_standby
archive_mode = on
archive_command = 'cp %p /<my-wal_archive-dir-here>/%f'
max_wal_senders =3
max_replication_slots = 3
wal_keep_segments = 512
hot_standby = on
$nano /etc/postgresql/12/main/pg_hba.conf
----------------------------------------------
....
host all barman <my-barman-ipaddress-here>/32 md5
host all streaming_barman <my-barman-ipaddress-here>/32 md5
The Barman Server (logged in as barman): ###############################
$psql -c 'SELECT version()' -U barman -h <my-ipaddress-here> postgres
version
-----------------------------------------------------------------------------
PostgreSQL 12.1 (Ubuntu 12.1-1.pgdg18.04+1) on x86_64-pc-linux-gnu,
compiled by gcc (Ubuntu 7.4.0-1ubuntu1~18.04.1) 7.4.0, 64-bit
(1 row)
$cat /etc/barman.d/pg.conf
[pg]
description = "Streaming Replication"
conninfo = host=<my-pg-server-ipaddress-here> user=barman dbname=postgres
streaming_conninfo = host=<my-pg-server-ipaddress-here>
user=streaming_barman dbname=postgres
backup_method = postgres
streaming_archiver = on
slot_name = barman
When I run/ I get:
$barman receive-wal --create-slot pg
ERROR: Cannot connect to server 'pg'
Thanks

The "streaming_barman" user should be a user with replication permissions
(if not already set, execute "ALTER USER streaming_barman REPLICATION")
and appropriate permission granted in "pg_hba.conf":
host replication streaming_barman <my-barman-ipaddress-here>/32 md5
> The Barman Server (logged in as barman): ###############################

Check the replication connection works with:
psql -c 'IDENTIFY_SYSTEM' 'host=<my-ipaddress-here> dbname=postgres user=streaming_barman replication=1'

Hi All,
Any idea how to prepare a script to populate multiple tables with random
data ?
Regards,
Swadesh

Hi Swadesh,

I recommend using Datafiller[1] for that. You just need to have the DDL
of the tables. Based on that the program will create a script that
inserts randomly generated data.
