hello again mr. warmerdam! 

yes now it works! i tried using ogr2ogr with "-nlt multipolygon"
option. i guess that solves that. thank you so much for this. :)

although i do have another problem. there are some shapefiles that
when i convert/insert, this error appears:

ERROR 1: INSERT command for new feature failed.
ERROR: numeric field overflow

ERROR 1: Terminating translation prematurely after failed translation
of layer <layer name here>

what does "numeric field overflow" mean? sorry for being a pest. my
problems just keep on coming. anyway thank you so much again sir for
your help.

have a nice day! :)
