At writing of a Layer with v.out.ogr in a Postgis DB a column „ogc_fid“ of
data type int4 is put on.
"GRASS 5.7.cvs:~ > v.out.ogr input=fields type=area dsn="PG:dbname=testdb"
layer=felder format=PostgreSQL
Exporting 65 areas...
GRASS Topology -> Simple Features conversion (may take some time)...
Processing area 65... 100%
67 features written
WARNING: 2 features without category written"
Integrating the Layer with v.external operats also as below is to be seen.
"GRASS 5.7.cvs:~ > v.external dsn="PG:dbname=testdb" layer=felder
output=Felder
Building topology ...
Feature: 67
Topology was built.
Number of nodes : 130
Number of primitives: 154
Number of points : 0
Number of lines : 0
Number of boundaries: 87
Number of centroids : 67
Number of areas : 87
Number of isles : 87
Number of areas without centroid : 20"
If I want to display the Layer, the following massage appears.

Even if I rename the column in „fid“ it does not work
