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 -------- 16011(1
row)
