I need to create a sequence in a stored procedure.
First I need to select a value from a table and set the sequence start 
value to that value.
We have a table that does not have a sequence on it, so I want to select 
the max value, increment by one
and then start the sequence there.
We have to do this on three databases, I have figured out how to do this 
in Oracle (build a string and the EXECUTE IMMEDIATE <myString>, but have 
not figured out how to do this with PostgreSQL.
any ideas?
thanks
J.V.
