Hello From: pgsql-general-owner@xxxxxxxxxxxxxx [mailto:pgsql-general-owner@xxxxxxxxxxxxxx] On Behalf Of Johann Spies Sent: Donnerstag, 2. März 2017 09:28 To: pgsql-general@xxxxxxxxxxxxxx Subject: column "waiting" does not exist I have no idea what is causing this message in the logs (PostgreSQL 9.6+177.pgdg80+1 on Debian): 2017-03-02 10:20:25 SAST [5196-1] [unknown] postgres postgres@template1 ERROR: column "waiting" does not exist at character 217 2017-03-02 10:20:25 SAST [5196-2] [unknown] postgres postgres@template1 STATEMENT: SELECT tmp.mstate AS state,COALESCE(count,0) FROM (VALUES ('active'),('waiting'),('idle'),('idletransaction'),('unknown')) AS tmp(mstate) LEFT JOIN (SELECT CASE WHEN waiting THEN 'waiting' WHEN state='idle' THEN 'idle' WHEN state LIKE 'idle in transaction%' THEN 'idle$ count(*) AS count FROM pg_stat_activity WHERE pid != pg_backend_pid() AND datname='data_portal' GROUP BY CASE WHEN waiting THEN 'waiting' WHEN state='idle' THEN 'idle' WHEN state LIKE 'idle in transaction%' THEN 'idl$ ) AS tmp2 ON tmp.mstate=tmp2.mstate ORDER BY 1; I do not know whether it is related but we recently get warnings about bloat in our system tables from the monitoring program. How do I fix the cause of this error message? The name of the column in pg_stat_activity has changed. I assume it comes from there?: 9.3: View "pg_catalog.pg_stat_activity" Column | Type | Modifiers ------------------+--------------------------+----------- datid | oid | datname | name | pid | integer | usesysid | oid | usename | name | application_name | text | client_addr | inet | client_hostname | text | client_port | integer | backend_start | timestamp with time zone | xact_start | timestamp with time zone | query_start | timestamp with time zone | state_change | timestamp with time zone | waiting | boolean | <--- state | text | query | text | 9.6: View "pg_catalog.pg_stat_activity" Column | Type | Modifiers ------------------+--------------------------+----------- datid | oid | datname | name | pid | integer | usesysid | oid | usename | name | application_name | text | client_addr | inet | client_hostname | text | client_port | integer | backend_start | timestamp with time zone | xact_start | timestamp with time zone | query_start | timestamp with time zone | state_change | timestamp with time zone | wait_event_type | text | <--- wait_event | text | <--- state | text | backend_xid | xid | backend_xmin | xid | query | text | Regards Charles Regards Johann -- Because experiencing your loyal love is better than life itself, my lips will praise you.
