There is something odd about how QGIS fetches values from the sequence:
The error message states that :
/2021-06-03T09:22:31 WARNING //Erroneous query: SELECT
nextval("sample_point_fid_seq"::regclass) returned 7 [ERROR: column
"sample_point_fid_seq" does not exist/
/ LINE 1: SELECT nextval("sample_point_fid_seq"::regclass)/
^
However - a correct call to the "nextval" function should loke like this:
*SELECT nextval('sample_point_fid_seq'::regclass)*
*Not* like this ( " contra ') :
*SELECT nextval("sample_point_fid_seq"::regclass)*
So the call fails twice : It calls a non-existing sequence and the
function argument should be 'sample_point_fid_seq'::regclass , not
"sample_point_fid_seq"::regclass

Hi,
You repeat this "ERROR: column "sample_point_fid_seq" does not exist"
-problem with:
Create very simple table to PostGIS (choose your own CRS):
CREATE TABLE IF NOT EXISTS sample_point
(
fid integer NOT NULL GENERATED ALWAYS AS IDENTITY,
wkb_point geometry(Point,3067),
name varchar,
CONSTRAINT sample_point_pk PRIMARY KEY (fid)
);
Add table to QGIS. Editing works, without errors.
If you tick on from project properties: "Evaluate default values on
provider side", error will happen:
2021-06-03T09:22:31 WARNING Erroneous query: SELECT
nextval("sample_point_fid_seq"::regclass) returned 7 [ERROR:

Hi Alexandre et al,
I re-create a database (sample one), create a new QGIS project,
add layers => same error. Maybe I open an issue in Github and I
can share more SQL and snapshots.

From that last error...
Are you sure your table was not changed after being loaded to
QGIS? It seems to expect a sequence that no longer exists.

Hi Andreas,
Trasnsactions groups are enabled: editing is working (not
in embedded forms) as expected.
If I enable "Evaluate default values.."-option, I will get
error:
2021-06-01T14:11:44 WARNING Erroneous query: SELECT
nextval("sample_point_fid_seq"::regclass) returned 7
[ERROR: column "sample_point_fid_seq" does not exist
LINE 1: SELECT
nextval("sample_point_fid_seq"::regclass)
Primary key of the geometry table is "fid" and it has been
defined as IDENTITY column (fid integer NOT NULL GENERATED
ALWAYS AS IDENTITY ( INCREMENT 1 START 1 MINVALUE 1
MAXVALUE 2147483647 CACHE 1 ).
I presume this evaluation of the default values is not the
solution for this case.

Hi Pekka,
Have you enabled the transaction mode in your project?
See menu "Project" --> "Properties" --> "Data Sources".
I usually enable all three check boxes:
- Automatically create transaction groups where possible
- Evaluate default values on provider side
- Trust project when data source has no metadata
The transaction mode allows to edit all layers from
the same data base connection (needs identical db
connection string and credentials) and - together with
"evaluate default values on provider side" -
immediately retrieves primary keys from the DB, so
that you can link objects immediately, without having
to save first.
Greetings,
Andreas

Hi folks!
I have a problem editing feature attributes in
embedded forms. Data is stored in PostGIS and I have
a simple 1:1 relationship with the geometry table and
an additional attribute table. QGIS version is 3.18.3
on Ubuntu.
I have created a custom form with a drag-and-drop
designer. I can edit additional attribute table
attributes in embedded form, but those edits are not
stored anywhere. I have to open a separate form and
then edit attribute values of the related attribute
table. This is quite annoying for the end user.
Any suggestions? Or should I write a better
description to the Github?
