Actually it is the problem:

https://www.pgadmin.org/docs/pgadmin4/4.16/editgrid.html

"If the table definition does not include an OID or a primary key, the 
displayed data is read only. "

As I recall Access has the same restriction.


I had to abandon plans to rollout a conversion to Postgres because of this 
problem, and so I'd like to solve it so we can do the switch relatively soon.

Here's the SQL on the table from pgAdmin:
CREATE TABLE public.tblaliquot
(
     aliquotid integer NOT NULL DEFAULT 
nextval('tblaliquot_aliquotid_seq'::regclass),
     preparationid bigint,
     datealiquotted date,
     rnaaliquottype bigint,
     sequencer character varying(4) COLLATE pg_catalog."default",
     aliquotlabel character varying(40) COLLATE pg_catalog."default",
     aliquotbarcode character varying(255) COLLATE pg_catalog."default",
     rnaaliquotconcentration double precision,
     originalvolume double precision,
     numberdefrosts integer,
     storagetype bigint,
     locationfreezer bigint,
     locationrow character varying(10) COLLATE pg_catalog."default",
     locationrack character varying(10) COLLATE pg_catalog."default",
     locationbox character varying(10) COLLATE pg_catalog."default",
     locationplate character varying(255) COLLATE pg_catalog."default",
     locationspace character varying(10) COLLATE pg_catalog."default",
     locationother character varying(60) COLLATE pg_catalog."default",
     aliquottedby bigint,
     comments text COLLATE pg_catalog."default",
     creationdate date,
     createdby bigint
)

The original code that created the table used AliquotID serial for the first 
field.

The sequence mentioned in the first field of the definition shows Current Value 
of 1 in the properties tab in pgAdmin, despite the large number of records.  
But the sequences associated with other tables also are very low, like 3 or 4.  
3 or 4 might be the number of records added after the initial creation.

This worked from psql:
INSERT INTO tblAliquot VALUES (55338, 6772, '2012-10-05 00:00:00', 6, E'A', 
NULL, NULL, 24.3,
    33, 0, 1, NULL, NULL, E'1', E'A', NULL,
    E'A1', NULL, 23, NULL, '2012-10-18 00:00:00', 55 );
