Hi,
You need to install plpython3u on your new server and also make sure to use python3. You need to make changes to your functions also to make them compatible with python3

Hi Team,

I am working on a project where we have applications run on old versions of postgres, we are using plpythonu in all Functions extension, 

Now we have upgraded postgres to latest which does not support plpythonu anymore, So we are facing an issue while restoring dump which has plpythonu, but latest postgres support only plpython3u. 

"pg_restore: error: could not execute query: ERROR:  language "plpythonu" does not exist"

How to change plpythonu to plpython3u in the dump file before pg_restore. or Does postgres have any option to handle directly via config. 

Thanks in Advance

Thanks,
Samson G
