Yeah, you're right :-(. 7.0 through 7.0.2 fail to do proper abort
processing if the client application disconnects partway through a
transaction. One of the effects is that temp tables aren't deleted.

You'd need to quote the name, eg
drop table "pg_temp.10863.1";
since dot isn't considered a regular identifier character.

Odd. Did you try to manually remove the pg_temp files at some point?
I think that 7.0.2 will let you do the drop anyway, but if not you
might have to create dummy files before dropping, eg
touch $PGDATA/base/relatorio/pg_temp.10863.1
and then drop the table.
7.0.3 will contain a fix for the failure-to-cleanup bug.
