error. When this happens, the target table may already have received
earlier rows in the load operation. Although these rows will not be visible
or accessible, they still occupy disk space. This may amount to a considerable
amount of wasted disk space if the failure happened well into a large
load operation. You may wish to invoke the <codeph>VACUUM</codeph> command
to recover the wasted space. For example, run the following command on
the master host after a load error:</p><codeblock>vacummdb <varname>dbname</varname> [<varname>table_name</varname>]</codeblock><p><codeph>VACUUM</codeph> reclaims storage occupied by deleted tuples. In
the master host after a load error:</p><codeblock>vacuumdb <varname>dbname</varname> [<varname>table_name</varname>]</codeblock><p><codeph>VACUUM</codeph> reclaims storage occupied by deleted tuples. In
normal operation, tuples that are deleted or obsoleted by an update are
not physically removed from their table; they remain present until a
<codeph>VACUUM</codeph> is done. Therefore it's recommended to do <codeph>VACUUM</codeph>
