[postgis-users] Missing primary key column.

[Byron Como]

The problem:
Missing primary key column in postgresql table imported into Quantum GIS.

Details:
43,000 object database created using Windows XP 32 bit, postgresql 8.4, 
postgis 1.4, Quantum GIS 1.5.
Daily backups using pgadmin.
Several db restores were performed on the XP system for various reasons 
(one time was to recover from a lightning strike). Restored data was 
good and project continued with no problems.
Recently upgraded to Windows 7 64 bit to be current and take advantage 
of the increased memory available.
Installed the same software as above.
The data in postgresql seems ok and can be manipulated normally - 
copied, pasted, deleted.
Importing a table into Qgis 1.5 or 1.6 results in layer with the primary 
key column missing. The data can't be manipulated completely. The table 
can be added to but deletions can't be performed. The primary key is 
gid, integer.

Corrective actions thus far:
Reloaded software many times giving great attention to the details of 
installation. Examined the data in pgadmin for anomalies. Nothing 
apparent. All seems correct. Posted to Quantum GIS mailing list. Nothing 
there.

Expected resolution:
Barring solution from mailing list suggestions, reinstall on Windows XP 
32 bit and continue with memory limitations as before. (Extra memory 
desired to make very large format high-resolution prints).
