Unfortunatley I am not useing a sequence directly, I am useing a text
field that is like this: 46-X
The X is a sequence, the 46 is site identification number, so that when
I replicate teh data to teh main site their is a way of knowing where it
came from, and also ensuring that the primary key for the table is
unique across several sites. It is created and inserted by a trigger.
So as you can see I don't actually know what the key will be before an
insert.
Currently I can then get the oid and then get the primary key for that
table row, but if OIDs are banished then I am screwed...
