"subquery" is not an SQL keyword.
<http://www.postgresql.org/docs/9.0/interactive/sql-keywords-appendix.html;

Nor is it a command all by itself.

Reading the documentation might help you:
<http://www.postgresql.org/docs/9.0/interactive/queries-table-expressions.html#QUERIES-SUBQUERIES;
<http://www.postgresql.org/docs/9.0/interactive/sql-expressions.html#SQL-SYNTAX-SCALAR-SUBQUERIES;
<http://www.postgresql.org/docs/9.0/interactive/functions-subquery.html;

Or try:
<http://lmgtfy.com/?q=SQL+subquery;
