Connecting MS Access to PostgreSQL Server - postgresql

Question

I'm having trouble with connecting to our postgres server. I was given the code used to connect ms access to our SQL Server. It shall be DSN-less, I have installed an ODBC-driver and now I'm stuck finding the correct connection string to write in access' vba code.
I know it has to be somewhat like this:
stConnect = "ODBC;Driver={PostgreSQL UNICODE};Data Provider=pgsqlODBC;hostaddr=[IP-adress];Port=61000;dbname=TE_TestFirst;user=admin;password=testtest;"
Or maybe like this:
stConnect = "ODBC;Driver={PostgreSQL UNICODE};Data Provider=pgsqlODBC;SERVER=[IP-adress];PORT=61000;DATABASE=TE_TestFirst;UID=admin;PWD=testtest;"
I have read that 64Bit-Pcs need to have been given the "Data Provider". Yet nothing works except the DSN version which we don't want. I've copied countless connection string from various sides, maybe I'm overseeing something?
I look forward to your replies and thank you in advance.

Answer 1

I have found a way to create a User-DSN within a MS Access module, which then I use to connect to the server. It is no very pretty code, but it works. For those who look for a similar solution:
'Creating User DSN
strAttributes = "Description=I did this myself" & Chr(13) & "Server=[Servername/ID]" & Chr(13) & "Database=TE_TestFirst" & Chr(13) & "Username=admin" & Chr(13) & "Password=***" & Chr(13) & "Port=61000"
DBEngine.RegisterDatabase "DSNnew", "PostgreSQL Unicode", True, strAttributes
MsgBox "DSN has been created", vbInformation
Connection String
stConnect = "ODBC;DSN=DSNnew;Server=[IP-adress];Port=61000;Database=TE_TestFirst;Uid=admin;Pwd=****;"
As you can see the information is embedded twice, which I really don't like but for the moment it is okay. You can check your created DSN with the ODBC Administrator.
You can find the original code here
Also this code is the way we get the tables from the server to MS Access. Although the example is about SQL Server, it works fine with PostgreSQL as well! (As I see now this side also provides a solution about creating DSNs)

Answer 2

I haven't been able to solve the matter with a connection string that is DSN-less, but with a DSN file like #Erik van Asmuth and #krish KM said.
The DSN file is located in my Documents folder (ODBC Administrator saved it automatically in this folder. You can move it anywhere, but then you have to write the path instead of the file name)
I open it via VBA Code in MS Access with the following connection String:
stConnect = "ODBC;FILEDSN=PGUnicode32;Server=[IP-adress];Port=61000;Database=TE_TestFirst;Uid=admin;Pwd=****;"
Access got a connection and loads the table TE-TestFirst. Thank you guys again. I will now try to connect via connection string without the file

Answer 3

In the end we did the following:
Using connection string "PostgreSQL Unicode(x32)" written like shown above + using a different script to connect to
It now works fine and DSN-less :)

Answer 4

Something like this:
stConnect = "Driver={PostgreSQL Unicode(x64)};Servername=dbtest;Port=5432;UID=postgres;Database=postgres;Password=****";
