Just wonder if anyone here uses Excel to connect to PG via ODBC.

I'm using it extensively as my platform to get data from PG/MSSQL
directly into excel. (Excel uses the msqry32.exe file which is like a
stripped down sql query tool and returns data directly into excel)

When using mssql, connecting from excel to mssql, I can get the query to
run in the background. Hence, a long running query will not interfere
with normal running of other excel works. Eg: Create new sheets,
graphing etc.

However, when trying to achieve the same thing using PG, somehow it
either :

1. PG/PG_ODBC doesn't parse/handle the request to do the query in the
2. I'm doing something wrong.

I'm partial to #1 as it works find on mssql.

Here's a sample query macro which you can stick into Excel. (alt-F11,
Module, Insert-New-Modules)

The Keyword here is "Refresh BackgroundQuery = True"

Sub macro1()

SQL = "Select * from public.tablename limit 5000"
ActiveSheet.QueryTables.Add(Connection:=Array(Array("ODBC;DRIVER={PostgreSQL Unicode};DATABASE=public;SERVER=;PORT=5432;UID=pguser;PWD=pguser")), Destination:=Range("A1"))
                .CommandText = SQL
                .Name = ""
                .FieldNames = True
                .RowNumbers = False
                .FillAdjacentFormulas = False
                .PreserveFormatting = True
                .RefreshOnFileOpen = False
                .BackgroundQuery = True
                .RefreshStyle = xlInsertDeleteCells
                .SavePassword = False
                .SaveData = True
                .AdjustColumnWidth = True
                .RefreshPeriod = 0
                .PreserveColumnInfo = True
                .Refresh BackgroundQuery:=True 
                End If
            End With
End Sub

I think this is like the last hurdle for me from moving from mssql to

Thanks and hopefully, there will be someone who uses it this way.
