# 52.2. BKI Commands

open `tablename`

  Open the table called `tablename` for further manipulation.

close [`tablename`]

  Close the open table called `tablename`. It is an error if `tablename` is not already opened. If no `tablename` is given, then the currently open table is closed.

create `tablename` (`name1` = `type1` [, `name2` = `type2`, ...])

  Create a table named `tablename` with the columns given in parentheses.

  The `type` is not necessarily the data type that the column will have in the SQL environment; that is determined by the `pg_attribute` system catalog. The type here is essentially only used to allocate storage. The following types are allowed: `bool`, `bytea`, `char` (1 byte), `name`, `int2`, `int2vector`, `int4`, `regproc`, `regclass`, `regtype`, `text`, `oid`, `tid`, `xid`, `cid`, `oidvector`, `smgr`, `_int4` (array), `_aclitem` (array). Array types can also be indicated by writing `[]` after the name of the element type.

  > Note: The table will only be created on disk, it will not automatically be registered in the system catalogs and will therefore not be accessible unless appropriate rows are inserted in `pg_class`, `pg_attribute`, etc.

insert [OID = `oid_value`] (`value1` `value2` ...)

  Insert a new row into the open table using `value1`, `value2`, etc., for its column values and `oid_value` for its OID. If `oid_value` is zero (0) or the clause is omitted, then the next available OID is used.

  NULL values can be specified using the special key word `_null_`. Values containing spaces must be double quoted.

declare [unique] index `indexname` on `tablename` using `amname` (`opclass1` `name1` [, ...])

  Create an index named `indexname` 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.

build indices

  Build the indices that have previously been declared.
