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.

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.
just about any sql is allowed from within a function, including CREATE
SEQUENCE.  functions can even create functions and execute them.
