The table <code class="literal">sql_sizing</code> contains information about
various size limits and maximum values in
<span class="productname">PostgreSQL</span>. This information is
primarily intended for use in the context of the ODBC interface;
users of other interfaces will probably find this information to be
of little use. For this reason, the individual sizing items are
not described here; you will find them in the description of the
ODBC interface.
