Patch for install with Postgresql

In i18nblocs.install :

case 'pgsql':
        db_query("CREATE TABLE {i18n_blocks} (
        delta varchar(32) NOT NULL DEFAULT '0',
        info varchar(64) NOT NULL DEFAULT '',
        type varchar(64) NOT NULL DEFAULT '',
        param int4 NOT NULL DEFAULT 0,
        PRIMARY KEY (delta))");
        db_query("CREATE TABLE {i18n_blocks_i18n} (
        bid serial4 NOT NULL,
        language varchar(12) NOT NULL DEFAULT '',
        module varchar(64) NOT NULL DEFAULT '',
        delta varchar(32) NOT NULL DEFAULT '0',
        PRIMARY KEY (bid,language))");
      break;

Works for me.
