+ 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 bootstrap catalogs, 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.
+ The table's row type OID (<code class="structname">pg_type</code> OID) can optionally
+ be specified via the <code class="literal">rowtype_oid</code> clause; if not specified,
+ an OID is automatically generated for it. (The <code class="literal">rowtype_oid</code>
+ clause is useless if <code class="literal">bootstrap</code> is specified, but it can be
+ provided anyway for documentation.)
