Yes the backend is working? The application is able to connect.
I set in /etc/hosts postgres servers IP and hostname on the pgpool servers
and on postgres servers I set pgpool IP and hostname in /etc/hosts. its
all on the same network so there should be any network issues.
It doesn¹t go through a firewall
Here shows the connection from pgpool to postgres
pgprod-con1 ~ pgpool $ psql -p 9999
Type "help" for help.
postgres=# show pool_nodes;
node_id | hostname | port | status | lb_weight | role
0 | pgprod-db | 5432 | 2 | 0.500000 | primary
1 | pgprod-rep | 5432 | 2 | 0.500000 | standby
I¹m not getting the error in my dev environment and in my RC environment I
only see the error on my standby pgpool server.
Our setup for all of our environments
2 pgpool servers (primary/standby)
2 postgres server (primary with streaming standby)
