Right, I understand that fully, and have used SQL inside a stored proc
before, but in this case as I mentioned, I need to first do a select
from a table to get a max value, store that in a variable and then use
that variable in a create sequence sql statement.

so I need to construct a string that contains the create sequence
statement and execute that string, at least this is the way it is done
in Oracle.

I do not know how to use a variable in a create sequence statement in
PostgreSQL.
