Added an 'alter sequence' line to the parser grammer which will simply skip over an alter sequence statement.
Added a select section to the parser.  This is to handle function calls that
may affect the tables during creation.

Added the setval function.  Unfortunately, nothing is being done with this
because the parser doesn't seem to handle sequences.

Skipping all COPY commands because they are not needed for schema creation.

Added a line each for revoking and granting permissions for a schema.  This
doesn't actually do anything with that information.

Applied patch submitted by Nathan Gray

Removes periods in an index/constraint name caused by schema.tablename being appended to the name.

Strips a schema from the table name during index/constraint creation because a schema-qualified table name is not allowed.
