Database query failed with error: column "node" does not exist

Hi there,

after installing PadeTitle2 (6.x-2.3) on Drupal 6.16 with Postgres 8.3.9 and PHP 5.2.6 the following message appears on alredy existing and new created nodes:
---snip---
* warning: pg_query() [function.pg-query]: Query failed: ERROR: column "node" does not exist LINE 1: ...T page_title FROM drupal6_page_title WHERE type = "node" AND... ^ in /xxxxxxxxxxx/development/includes/database.pgsql.inc on line 139.
* user warning: query: SELECT page_title FROM drupal6_page_title WHERE type = "node" AND id = 26 in /xxxxxxxxxxx/sites/all/modules/page_title/page_title.module on line 390.
---snap---
(Directories are x'ed).

Under "Content management" -> "Page title" I added "[page-title]" to the related content types.

My trial to solve it:
- add page title: Same error.

Any hint to solve it?

thx in advance.
regards,
Maschi
