Overwrites the original method to specify SQL statement
{@link #SQL_FOREIGN_KEYS} as replacement because the JDBC driver for
PostgreSQL does not handle matching table names.

@param _con          SQL connection
@param _sql          SQL statement (not used)
@param _cache4Name   map used to fetch depending on the table name the
related table information
@throws SQLException if foreign keys could not be fetched
