Oh no, thank for this finally I found the .shx it was just the
curiosity of understanding something new :)

Well, no. At least, I didn't say so, and I don't think enough has been
said in this thread to definitively arrive at that conclusion. Only
the creator(s) of shp2pgsql will be definitively able to establish the
above. What we can say definitively is that you *can* read both the
geometry and its corresponding attributes using whatever method as
long as you remember the order of the entries in the respective files.
You just can't do it with a program that uses the SHX as the
cross-reference.
In the meantime, there could be a multitude of reasons by shp2pgsql
can't read your file.
In other words, while we all have learned something new, you are still
at square 1.
:-(
Thanks a lot

It is only required if you want to read the data through the index.
You are absolutely correct on both counts. I realized my misleading
message after I had sent it as I have been happily reading DBF files
and modifying them using Perl directly and the parent Shapefile has
been ok. Thanks for pointing it out.
To the OP -- one of them (between SHP and DBF) is indexed starting
at
0 and the other one starting at 1 (I always forget which one is
which).
Perhaps shp2pgsql does exactly that... read the attributes for each
shape via the index.

Hello all, is it normal that trying to convert a shape into sql
with
shp2pgsql I have an error stating that i need the .shx index
file? Is there
an option for importing having only the .shp file?
Thanks

The .shx file is the link between the geometry (.shp) and the
attributes (.dbf). These three are the minimum necessary
components of
an ESRI Shapefile. If your .shx/.dbf are missing then you have any
incomplete Shapefile.
