procpid for temp schema

[ashok raj <ashokexplorer@xxxxxxxxx>]

Hi , 

         is there a way that we could find which procpid or connection that has created a particular temporary  schema (pg_temp_*) ?.

         In one of our db a temporary schema (pg_temp_48) was using more than 200GB of disk space  and how to find the connection which has created the temp schema,  ?
