> There seems to be an error on the SYSCS_UTIL.SYSCS_INPLACE_COMPRESS_TABLE
> documentation or the implementation itself when passing the following
> arguments:
> PURGE_ROWS
> If PURGE_ROWS is set to a *non-zero* value, then a single pass is made
> through the table which will purge committed deleted rows from the table.
> <snip>
> DEFRAGMENT_ROWS
> If DEFRAGMENT_ROWS is set to a *non-zero* value, then a single defragment
> pass is made which will move existing rows from the end of the table towards
> the front of the table.
> <snip>
> TRUNCATE_END
> If TRUNCATE_END is set to a *non-zero* value, then all contiguous pages
> at the end of the table will be returned to the operating system.
> <snip>
> The implementation only checks if the above arguments are 1s.
