Description:

I have my application working on psql ODBC driver, connecting my .net code
to the postgreSQL server and the connection string is as follows:

<add name="abc"
connectionString="DSN=DriverName;UID=U_name;Pwd=Paas;POOLING=true;MIN POOL
SIZE=1;MAX POOL SIZE=25;" providerName="SYSTEM.DATA.ODBC" />

I have set my connection timeout = 120; (in seconds)

I want to maintain the execution process to be upto 25 and not exceeding it.
Hence I used connection pooling. But it is not working. The connection limit
is exceeding the MAX POOL SIZE.

Please help me out on this one. What can I do to get the connection limit to
25 only and not exceeding it.

I am using :

1) .Net 4.0 Version.

2) psqlODBC driver is 9.5.3(64-bit).

3) pg-Admin is 9.5.3.
