Ben has the solution.
Indeed, the geometry column primary key was messed up. I deleted the old
one, added the gid serial integer column and set it to the primary key.
Works like a charm.

Byron,
A little bit more information may help here - what do you mean by 'importing'
the table into QGIS? Have you checked that the primary key is unique - and such
a constraint exists on the table definition? and that the column is in the
geometry_columns table - you may want to try populate_geometry_columns()
function.
maybe post the output of \d tablename.
cheers

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).
