There is actually no way to know the name from the table name, but if
there is only one temp table, pg_class will have the oid of the backend
in the table name. To get the backend pid, you can use libpq's
PQbackendPID() function or do this:

create function getpid () returns int as '/shlib/libc.so'
language 'c';

test=> select getpid();
getpid
