Me, too. This problem is present as far as I use QGIS together with 
PostGIS (QGIS 1.5 maybe). As far as I can remember only DDL statements 
(e.g. ALTER TABLE) are affected, whereas e.g. SELECT works as expected.
However I do not remember running into this in the last couple of months 
but this was maybe just luck :)
What has to be investigated, too, is if it happens with the same db user 
(role) accessing a table through QGIS and pgadmin. Background is I have 
dozens of db roles accessing the db with QGIS and as said above did not 
run into this problem recently when administrating the db with pgadmin.
Anybody has an idea what the reason is? Does QGIS lock a table so it 
cannot be altered?
