Unknown subdirectories in postgres base directory

[Howard Cole <howardnews@xxxxxxxxxxxxx>]

Hi All,

I am using postgres 8.0 on a windows server and I create and delete 
database frequently. However I have noticed that the number of 
subdirectories in the base directory does not reflect the number of 
databases.

Can I delete the directories that do not correspond to the OIDs in:

select oid, datname from pg_database;

Thanks.

Howard
