  <para>
   <function>pg_insert</function> inserts the values
   of <parameter>values</parameter> into the table specified
   by <parameter>table_name</parameter>.
  </para>
  <para>
   If <parameter>flags</parameter> is specified,
   <function>pg_convert</function> is applied to
   <parameter>values</parameter> with the specified flags.
  </para>
  <para>
   By default <function>pg_insert</function> passes raw values.
   Values must be escaped or the <constant>PGSQL_DML_ESCAPE</constant> flag
   must be specified in <parameter>flags</parameter>.
   <constant>PGSQL_DML_ESCAPE</constant> quotes and escapes parameters/identifiers.
   Therefore, table/column names become case sensitive.
  </para>
  <para>
   Note that neither escape nor prepared query can protect LIKE query,
   JSON, Array, Regex, etc. These parameters should be handled
   according to their contexts. i.e. Escape/validate values.
