- installiert I pgAdmin III Version 1.22
- On Server haben postgresql 9.4 haben: D: \ install \ wildfly-8.2.0.Final \ modules \ org \ postgresql \ main \ postgresql-9.4. 1208.jar
- Auf pgAdmin habe ich PostgreSQL 9.5.2 wie unten dargestellt:
Um das Problem, das ich versuche zu lösen bin die max_prepared_transactions zu erhöhen, wie der Hinweis sagt:
1) In den pgAdmin Client Tools> Serverkonfiguration> postgresql.conf Ich habe die max_prepared_tranzaction bis 10 
dann tryed ich, indem sie vor, um den Server neu zu starten:
- tools> Serverkonfiguration> postgresql.conf> Datei> neu laden Server und ich habe auch versucht,
- pgAdmin III> Datei> Konfiguration neu laden
2) In C: \ Program Files (x86) \ pgAdmin III \ 1,22 \ i18n \ pg_settings.csv Ich sehe dies: 
aber ich don‘ Ich weiß, ob es für die Bearbeitung gut ist.
Nach diesen Schritten bleibt der Fehler bestehen.
Dann habe ich versucht postfresql.config zu finden und ich habe die Abfrage ausgeführt, die Sie unten sehen können: 
aber ich konnte nicht finden die Datei (wie Sie oben im Bild sehen).
Kann mir jemand eine Lösung geben, um den Fehler zu beheben? Ich denke, der Parameter max_prepared_transaction sollte erhöht werden, aber ich kann die postgresql.config-Datei nicht finden.
Nur um sicher zu sein, schließen Sie Ihre Verbindungen, nachdem Sie sie verwendet haben, nicht wahr? –
Ja, ich schließe sie. –
