<dd>
<p> Create a table named <em class="replaceable"><code>tablename</code></em>, and having the OID
<em class="replaceable"><code>tableoid</code></em>,
with the columns given in parentheses.
</p>
<p> The following column types are supported directly by
<code class="filename">bootstrap.c</code>: <code class="type">bool</code>,
<code class="type">bytea</code>, <code class="type">char</code> (1 byte),
<code class="type">name</code>, <code class="type">int2</code>,
<code class="type">int4</code>, <code class="type">regproc</code>, <code class="type">regclass</code>,
<code class="type">regtype</code>, <code class="type">text</code>,
<code class="type">oid</code>, <code class="type">tid</code>, <code class="type">xid</code>,
<code class="type">cid</code>, <code class="type">int2vector</code>, <code class="type">oidvector</code>,
<code class="type">_int4</code> (array), <code class="type">_text</code> (array),
<code class="type">_oid</code> (array), <code class="type">_char</code> (array),
<code class="type">_aclitem</code> (array). Although it is possible to create
tables containing columns of other types, this cannot be done until
after <code class="structname">pg_type</code> 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.)
</p>
<p> When <code class="literal">bootstrap</code> is specified,
the table will only be created on disk; nothing is entered into
<code class="structname">pg_class</code>,
<code class="structname">pg_attribute</code>, etc, for it. Thus the
table will not be accessible by ordinary SQL operations until
such entries are made the hard way (with <code class="literal">insert</code>
commands). This option is used for creating
<code class="structname">pg_class</code> etc themselves.
</p>
<p> The table is created as shared if <code class="literal">shared_relation</code> is
specified.
It will have OIDs unless <code class="literal">without_oids</code> is specified.

</span></dt>
<dd>
<p> Insert a new row into the open table using <em class="replaceable"><code>value1</code></em>, <em class="replaceable"><code>value2</code></em>, etc., for its column
values and <em class="replaceable"><code>oid_value</code></em> for its OID. If
<em class="replaceable"><code>oid_value</code></em> is zero
(0) or the clause is omitted, and the table has OIDs, then the
next available OID is assigned.
</p>
<p> NULL values can be specified using the special key word
<code class="literal">_null_</code>. Values containing spaces must be
double quoted.

<dd><p> Create an index named <em class="replaceable"><code>indexname</code></em>, having OID
<em class="replaceable"><code>indexoid</code></em>,
on the table named
<em class="replaceable"><code>tablename</code></em>, using the
<em class="replaceable"><code>amname</code></em> access
method. The fields to index are called <em class="replaceable"><code>name1</code></em>, <em class="replaceable"><code>name2</code></em> etc., and the operator
classes to use are <em class="replaceable"><code>opclass1</code></em>, <em class="replaceable"><code>opclass2</code></em> 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.
