[Qgis-user] DB manager error

[Gustavo Martínez]

Hi, 

I'm using QGIS 2.99.0-Master rev. b2587b7 on Ubuntu 16.04 64bits.

When I tried to open a SQL query on a POSTGIS database I've got the following error while trying to open the saved connection to the database: 

2016-10-28T15:58:35	1	Traceback (most recent call last):

I can load postgis layers from the same connection without problems.
What can I do?
Thanks,
