Alle prese con PGBouncer

Question

Ho Postgres 9.2 e PGBouncer (la versione fornita con il "Stack Builder"). Ho un'applicazione .NET che si collega tramite NPGSQL versione 2.0.12 su una macchina Win7.

La mia applicazione può connettersi felicemente direttamente al server Postgres, ma non riesce sempre a connettersi tramite PGBouncer.

La mia stringa di connessione a NPGSQL (dopo una certa sostituzione è)

Sslmode=Prefer;Timeout=40;Server={0};Port={3};User Id={4};Password={1};Database={2};Pooling=False;

(Ho anche provato a connettermi a PGBounce con protocollo = 3 esplicitamente e questo non ha funzionato.)

La riga del database da pgBounce Ini è:

[databases]
something = host=localhost port=5433 dbname=somethingelse user=someone password=aaa

e in UserList.txt ho "qualcuno" "AAA" come richiesto.

Quando la mia app esegue l'NPGSQL dice "Connessione con forza" e il registro degli errori di PGBouncer dice:

L'eccezione NPGSQL dice: (Da un file di registro nell'app, l'eccezione più alta segue le eccezioni nidificate):

Exception message:  Unable to read data from the transport connection: An established connection was aborted by the software in your host machine.

Inoltre, Window Firewall è spento e anti -virus ho spento temporaneamente.

Il file Conf HBA per Postgres ha:

host    all             all             127.0.0.1/32            md5

host    all             all         fe80::1/16                  md5

Ho cercato su Google e non ho trovato alcuna soluzione. Aiuto! Grazie.
