Thank you Jason for your answer.
I've granted usage on schema topology to my user -> same problem. I even
granted PUBLIC.
There is something 'wrong' with the passed request itself as it fails in
pgadmin as well (see it below).
I have a very basic test.qgz file. I launch it with 3.4.13 (I've updated
all my qgis versions), open the browser, connect to my db and see the
tables. Same file, launched with 3.10.0, open browser, connect to my db
(same profile so I guess same qgis-auth.db file I suppose) and get the
'failed to get layers' as described in the bug. I can see the sql request
which failed and that one doesn't work either in pg_admin. Unfortunately
the sql request passed with 3.4.13 is not displayed.

I have postgresql 9.6, postGIS 2.3
Kind regards

I think your issue sounds like what I experienced and from what I dug up
it can be as simple as what version of Postgres you were using (I was
using
Postgres version 10.10) not allowing any access to the "topology" schema.
https://github.com/qgis/QGIS/issues/32483
I fixed by running the following SQL command (replace *USERNAME as the
username* you are using to connect to postgres):
*GRANT USAGE ON SCHEMA topology TO USERNAME;*
it was also suggested you could instead give access to public but I'm not
sure if that is as secure but maybe other issues are created if public
doesn't have access, this is not my area of expertise.
GRANT USAGE ON SCHEMA topology TO PUBLIC;
Hope that helps.

Good afternoon,
Windows 8.1 pro 64 bits
QGIS version 3.10.0-A Coruña QGIS code revision 6c816b4204
I have a postgresql db with Postgis enabled to which I connect using a pg
service.
It was working fine with the default profile.
I created a new profile (settings/user profiles). My projects were still
displayed (tables located in the db) and looked ok.
But when I wanted to add a new table from datasource manager/postgresql I
was prompted the first time to create a connection. I created the same
one
as I had for the default profile. I tested the connection and it passed.
I
clicked to 'connect' and nothing happened: no table list displayed. I
checked with DB/DB manager and I can see my tables.
I switched back to the former default profile: same behaviour (no tables
listed).
There are different qgis-auth.db files (different sizes) in each profile
folder of C:\Users\<myuser>\AppData\Roaming\QGIS\QGIS3\profiles (don't
know
how to read them though)
In the logs I found the following messages (PostGIS section):
2019-11-16T12:27:02 WARNING NOTICE: row number 0 is out of range
0..-1
2019-11-16T12:28:20 WARNING Erroneous query: <long query> [ERROR:
permission denied for schema topology
2019-11-16T12:28:20 WARNING NOTICE: WARNING: there is no
transaction in progress
2019-11-16T12:28:20 WARNING Unable to get list of spatially
enabled tables from the database
I don't have any problem with the default user and QGIS version
3.4.13-Madeira
(I have not tried to create another profile with 3.4.13 because I need a
working version of qgis).
The error message seems to point toward a lack of permission, but that
same user can run that query within pgadmin without any problems.
Any idea where to look? I looked on internet but to no avail ...
Thank you in advance
