I updated to latest version of PGNP SE (from 184.108.40.20632) and now receive error from linked server:
"Cannot obtain the schema rowset "DBSHEMA_TABLES" for OLE DB provider PGNP for linked server...
The provider supports the interface, but returns a failure code when it is used.(Microsoft SQL Server, Error:7311)"
When I reinstall 220.127.116.1132 I connect to the linked server without having to recreate the liked server object.
PGNP SE is running on MSSQL 2008
