Tested on Ubuntu 11.04, Libo3.5 RC2, psql 8.4 & 9.1 Open ODB connected to postgresql server Open any table in edit mode. No ability to edit properties for any existing column. [NOTE: drop column and add column work w/o problem]
Confirmed. Setting to "enhancement" since AFAIK this never worked with PostgreSQL-SDBC in the past. Setting low priority as I'm going to focus on data manipulation issues before data definition issues. (data definition can conceivably be done with SQL statements rather than GUI and/or separate PostgreSQL-specific GUI).
I tested on debian stable 7 x86-64. I can confirm this bug on all versions of LO up to 4.2 and on all versions of the postgresql sdbc driver (packaged in debian as libreoffice-sdbc-postgresql) up to the one intended for LO 4.1
