Help needed : temp tables.

I'm having problems with temporary tables in postgre.

I've been using Postgre 7.02 in a red hat 6.2 and I'm accessing using Delphi
5 + Winzeos Postgre Components. I've been using for some mounths and now I
checked that there are lots of temp tables in my system. These tables where
created by my application and I think everytime it crashed the temp tables
where not removed.

How can I delete a 'zombie' temp table? I tried to drop these tables, but
the following message appeared, per example :


relatorio=# \dS
           List of relations
       Name        |  Type   |  Owner
-------------------+---------+----------
...
 pg_rules          | view    | postgres
 pg_shadow         | table   | postgres
 pg_statistic      | table   | postgres
 pg_tables         | view    | postgres
 pg_temp.10050.18  | table   | postgres
 pg_temp.10050.19  | table   | postgres
 pg_temp.10050.20  | table   | postgres
 pg_temp.10863.0   | table   | postgres
 pg_temp.10863.1   | table   | postgres
 pg_temp.10863.2   | table   | postgres
 pg_temp.10863.3   | table   | postgres
 pg_temp.10863.4   | table   | postgres
 pg_temp.10863.5   | table   | postgres
 pg_temp.10863.6   | table   | postgres
...lots and lots more

relatorio=# drop table pg_temp.10863.1;
ERROR:  parser: parse error at or near ".10863"


And if I try vacuum verbose analyze, I get this message:

NOTICE:  --Relation pg_temp.10863.0--
NOTICE:  mdopen: couldn't open pg_temp.10863.0: No such file or directory
ERROR:  cannot open relation pg_temp.10863.0


Does someone know how to solve this problem?

Thanks!
