Create a table named tablename, and having the OID tableoid,
with the columns given in parentheses. The following column
types are supported directly by bootstrap.c: bool, bytea, char
(1 byte), name, int2, int4, regproc, regclass, regtype, text,
oid, tid, xid, cid, int2vector, oidvector, _int4 (array), _text
(array), _oid (array), _char (array), _aclitem (array). Although
it is possible to create tables containing columns of other
types, this cannot be done until after pg_type has been created
and filled with appropriate entries. (That effectively means
that only these column types can be used in bootstrapped tables,
but non-bootstrap catalogs can contain any built-in type.) When
bootstrap is specified, the table will only be created on disk;
nothing is entered into pg_class, pg_attribute, etc, for it.
Thus the table will not be accessible by ordinary SQL operations
until such entries are made the hard way (with insert commands).
This option is used for creating pg_class etc themselves. The
table is created a
