Dear all,
I have a table with 21 columns.
Primary key is done with 20 of these colums.
I have 3.313 records.
I don't know why, but I'm not able to update some of these records.
I don't understand, it seems that I'm not able to fetch.
It happens with Pgadmin, with Python Psycopg2 and also through Libreoffice Base.
Looking to the properties of the table in Pgadmin, I can see only the estimated number
of rows. Counted rows are 'not counted'.
