Hi Jürgen,
Thanks for that.
I did some testing following your e-mail.
After creating a layer in db_manager, I tried to load it and got an error:
dbname='testes'(...)key='r_table_catalog'
table="pg_temp_7"."nnn2" sql= is an invalid layer - not loaded
I guess I'll have to think of an

QGIS and the db_manager use separate sessions. I didn't tr
For me the advantage is simple: I have a few plpgsql functions which create
tables with variables computed from some quite large tables. I then use
these tables as input to create other result tables (with geometry).
And yes, the advantage is not to deal with multiple deleting in the end of

ok - wasn't aware of that.
What is the advantage of using these temp tables? That you do not have
to deal with deleting the table?
I am not too familiar with the internals of db-manager. Does it

What do you mean by "temp tables"?
There are no "temp tables" in a database. Either it is a table, a view

The thing is I have some custom functions which output temp tables. And it
would be useful to be able to explore these tables in db-manager.
I guess it shouldn't be too difficult to tweak dbmanager.
I was looking at the source code for but unfortunately my knowledge of
pyqgis is not quite there (m
Hi,
You can load query results in db-manager.
Just create a query in db-manager, select the primary key column and the
geometry column and load it.
Works fine for me.

Hi,
Is there a way to access temporary tables through db-manager?
