LoadTypesMapping : Value was either too large or too small for an Int32 - using npgsql in excel 64bit power query

[sean.v...@lendico.de]

Hi, I am using npgsql as a connector (https://support.office.com/en-us/article/Connect-to-a-PostgreSQL-database-Power-Query-bf941e52-066f-4911-a41f-2493c39e69e4?CorrelationId=1e7dd3e7-2adc-4334-93c9-1bb4283ddd9f&ui=en-US&rs=en-US&ad=US) in Excel 64 bits Power Query, and I have hit a problem.


I get "Value was either too large or too small for an Int32" during the inital "login".

[ I am inexperienced in nppgsql, and used http://pgfoundry.org/frs/download.php/3796/Setup_Npgsql-2.2.3.0-r2-net40.exe to install (also tried .net 4.5 version)
]

So 1 question is where is the error coming from (database/nppgsql/excel)
( and obvioulsy best if soemone knew solution)

[DataSource.Error] Value was either too large or too small for an Int32.
