I used PS to pull the data from mssql  to Postgres dumping data to csv. I then used csv to load Postgres and the table that has Bytea

# Convert the image data to a base64 string  -- powershell
    $base64Image = [Convert]::ToBase64String($row.ImageSource)

AFter data was loaded the developer said in his app frontend that the Image wouldn't open thru his code. -- I'm trying to get that code to help debug

He said the size of the array is 1368. from bytea The size coming from the SQL-Server db is 46935 and the image correctly appears...

Could that be caused by my PS dump to csv process or maybe still a code(frontend) issue..

Still trying to figure out using a single record if data loaded to the bytea field matches the mssql record.

I tried to use the tool SimplySql to connect mssql to postgresql to transfer data but it failed  ... 

any help would be appreciated..

I use this: https://blog.cleverelephant.ca/2021/04/psql-binary.html
But I don't know if that translates to PowerShell.
