I studied their webpages.
1. Zen Cart - GPL license, php, mysql
Seems to have lot of modules and users. Fresh updates.
Installation manual in their web site wrote that it is for MySql only.
Site search for PostgreSQL returns no results.
2. OSCommerce - GPL license, php, mysql. Last change in Jan
2008, 2 releases per year.
Search for Postgres/PostgreSQL in doc does not return results.
3. Ubercart + Drupal GPL license. Drupal developers accept patches for
PostgreSQL but do not support it.
Ubercart seems to be developed by single company which migrated from
OSCommerce. Fresh updates.
Forums contain some messageas about Ubercart usege with PostgreSQL.
4. Ecommerce http://www.drupalecommerce.org/
Site contains few information, most pages redirect to drupal page.
Last update was 30 May
Seems to be incomplete and not finished.
So the only way is to use Ubercart + Drupal, right ?

Probably I do'nt need transactions.
