[pstricks] dbicons: entities positioning

[Olga Lyashevska]

Dear All,

In dbicons I am trying to get the entity 'tbl_std' on one horizontal line
with the entity 'tbl_lvl' and the same for 'tbl_dsc' and 'tbl_indx'
So that they will be positioned in the corners of imaginary rectangle.

At this moment they are skewed. Could you suggest anything?

Thanks in advance,
Olga
