Subject Releasing of Database pages forcibly

We are facing some issues with the release of database pages after
delete all records in the table.

Since there are no temporary tables in Firebird, like ORACLE, we are
inserting updating data in the normal tables and then deleting when the
process is completed. However, there seems to be some issue with the
Firebird Server 1.5.3 as it does not release the pages after all the
records are deleted. When we check the RDB$PAGES table it still shows
pages against these tables with 0 records. As a result, the subsequent
operations on these tables take a performance hit as if data still

Is there anyway in which we can release / de-allocate these pages to the
operating system. If this is a genuine issue with this version, could
you please suggest any other technique to circumvent this problem?

Thanks and Regards,
