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
