Show replication status in PostgreSQL

https://www.niwi.nz/2013/02/16/replication-status-in-postgresql/

 

select client_addr, state, sent_location, write_location,
        flush_location, replay_location from pg_stat_replication;

This query can output can be like this:

postgres=# select client_addr, state, sent_location,write_location, flush_location, replay_location, sync_priority from pg_stat_replication;

Disable Streaming Replication without restarting either master or slave

I understand the way things work currently, but would it not be more
convenient to let the replication be stopped and started from SQL commands
like:

On Master:

select pg_pause_streaming_replication(slave_fqdn);
select pg_resume_streaming_replication(slave_fqdn);

On Slave:

select pg_pause_streaming_replication();
select pg_pause_streaming_replication();

If Cascaded Streaming Replication is confugured, then

On Slave:

select pg_start_streaming_replication(cascaded_slave_fqdn);
select pg_stop_streaming_replication(cascaded_slave_fqdn);

Or an OS executable [ either in the core or a contrib module] like

pg_replication -p primary_fqdn -s slave_fqdn -a pause
pg_replication -p primary_fqdn -s slave_fqdn -a resume
pg_replication -p primary_fqdn -s slave_fqdn -a setup

[ the last one would awesome; and i do not think that it is impossible, and
would be loved by one and all ]

Erreur EXP-00008, ORA-04063, ORA-06508, EXP-00083 PL/SQL: could not find program unit being called: "WMSYS.LTUTIL"

Alors lorsque je faisais un export classique avec exp, j'avais cette erreur là :

 

EXP-00008, ORA-04063, ORA-06508, EXP-00083 PL/SQL: could not find program unit being called: "WMSYS.LTUTIL"

 

Je suis tombé sur cette page :

Qui ne m'a pas aidé.

 

Par contre en cherchant bien je suis tombé sur ça :

et cela a résolu, mon pb.
