i am getting ERROR: column pd.adsrc does not exist at character 89 when
ever i am trying to execute the query from my application with posgreSQL12.2
version.it works fine with 11.
Its not a bug. Catalog structures change. The version 11 user documentation note for this catalog table even tells you not to use the column and provides an alternative.
You can probably find more info as to why now by looking at the git commit that removed it (and maybe nearby) but we’ve been getting rid of quite a bit of cruft recently.
