[bootstrap

] [rowtype_oid
oid
] (name1
= type1
[FORCE NOT NULL
| FORCE NULL
] [, name2
= type2
[FORCE NOT NULL
| FORCE NULL
], ...])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 bootstrap catalogs, 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 as shared if shared_relation
is specified. The table's row type OID (pg_type
OID) can optionally be specified via the rowtype_oid
clause; if not specified, an OID is automatically generated for it. (The rowtype_oid
clause is useless if bootstrap
is specified, but it can be provided anyway for documentation.)
open
tablename
Open the table named tablename
for insertion of data. Any currently open table is closed.
close
tablename
Close the open table. The name of the table must be given as a cross-check.
insert
(
[oid_value
] value1
value2
... )
Insert a new row into the open table using value1
, value2
, etc., for its column values.
NULL values can be specified using the special key word _null_
. Values that do not look like identifiers or digit strings must be single-quoted. (To include a single quote in a value, write it twice. Escape-string-style backslash escapes are allowed in the string, too.)
declare
[unique
] index
indexname
indexoid
on
tablename
using
amname
(
opclass1
name1
[, ...] )
Create an index named indexname
, having OID indexoid
, on the table named tablename
, using the amname
access method. The fields to index are called name1
, name2
etc., and the operator classes to use are opclass1
, opclass2
etc., respectively. The index file is created and appropriate catalog entries are made for it, but the index contents are not initialized by this command.
declare toast
toasttableoid
toastindexoid
on
tablename
Create a TOAST table for the table named tablename
. The TOAST table is assigned OID toasttableoid
and its index is assigned OID toastindexoid
. As with declare index
, filling of the index is postponed.
build indices
Fill in the indices that have previously been declared.
