You can add a second table (pseudo code)
inventory_detail
pk serial primary key
fk_inventory integer foreign key (inventory.pk)
detail_name text
detail_value text
and then - instead of creating columns in table inventory -
add rows to the inventory_detail table where .detail_name
would hold what otherwise would be the column name of the new
column in inventory and .detail_value the value you would
have put into the new column in table inventory. The
fk_inventory column would hold the primary key of the row in
the inventory table this inventory_detail row belongs to.
Just a suggestion.
