Something strange is happening with my new created tables in Postgres, I can add data to them, but I cannot use PgAdmin to edit the any row.
This is my table columns description:
After executing the query to view all table rows this is what I can see:
Save button is disabled to update my table rows. But this is happening only with my new created tables, as you can see, I have other tables where I'm able to edit rows, for example at this table of Users:
Found the problem! That was happening, because I didn't select any of the columns as 'Primary key':

I’m trying to drop temporary tables created by Redshift.
I use the following query to find all the temp tables in the cluster:
select name, count(distinct id)
from stv_tbl_perm
where temp = 1
group by 1
The table i'm trying to drop called $stg_inappshourly.
I've tried to drop it in both of the following methods:
drop table $stg_inappshourly
drop table stg_inappshourly
The first one returns a syntax error. The second one drops the actual table.
Any ideas how to drop it?
Solved.
The reason this table kept existing is because its session had an error and it didn't close as expected.
The only way I found to remove this table was rebooting the Redshift instance.
I am using PostgreSQL 9.6. I have created a table with create query.
But when i checked in left panel of pgAdmin, under table i found more six columns named tableid,cmax,xmax,cmin,xmin and ctid.
When i searched about this, I found that these are OIDs column and does not affect to data on other columns.
I have to import data into this table. So after selecting table, from right click i got option for import/Export. So from that i am importing .csv file.
But when i tried to import the data in table, i am getting error like,
ERROR: column "tableoid" of relation "account" does not exist
Please suggest me how to eliminate these OID columns from table.
You must be missing some column that is present in the csv named "tableoid".
In this case ,TABLE according to the import file must be created first. IF there is no prior table , it wont work. This may help.

I'm trying to import a CSV file with column names "Zip Code", "2010 Population", "Land-Sq-Mi" and "Density per Sq Mile" into my test table, which is named derp--that's why I have the drop statement at the beginning, so I don't replicate any rows and can start clean in each iteration.
Code is as follows:
DROP TABLE derp;
CREATE TABLE public.derp("Zip Code" varchar, "2010 Population" integer, "Land-Sq-Mi" numeric, "Density Per Sq Mile" numeric);
COPY derp("Zip Code", "2010 Population", "Land-Sq-Mi", "Density Per Sq Mile")
FROM '/home/michael/PycharmProjects/cmsDataProject/Zipcode-ZCTA-Population-Density-And-Area-Unsorted.csv'
DELIMITER','
CSV HEADER;
This does a fine job of importing the actual data, but it leaves the column headers blank in the pgadmin III data view. I looked at the source file in Nano--the headers are there, and if they weren't the query would have thrown a syntax error telling me that there was no relation for the column I was trying to import into.
Any ideas about what I'm doing wrong?
Edit: I would like pgadmin III data view to display the header names, and possibly a way to verify that the columns are actually named even if they aren't being imported and not displayed. To reiterate, every row after the headers is intact and in view, just the header row is blank.
Edit 2: When I CREATE TABLE public.derp(); and then manually add the columns, they show correctly in the data view. Something about the multi-line query statement was causing the breakage.
So pgadmin is not showing the column names but it's showing the data?
If you open a table in pgadmin, then alter the table, but keep the table window open, it seems to lose the column names.
Close the window with the table. Click the tables icon in the pgadmin tree view and refresh the tables, and reopen the table window.
I am new to postgreSQL. Is there any way to insert row in postgreSQL pgAdmin without using SQL Editor (SQL query)?
The accepted answer is related to PgAdmin 3 which is outdated and not supported.
For PgAdmin 4 and above, the application is running in the browser.
After you create your table, you have to make sure that your table has a primary key otherwise you couldn't edit the data as mentioned in the official documentation.
To modify the content of a table, each row in the table must be
uniquely identifiable. If the table definition does not include an OID
or a primary key, the displayed data is read only. Note that views
cannot be edited; updatable views (using rules) are not supported.
1- Add primary key
Expand your table properties by clicking on it in the pgAdmin4 legend. Right-click on 'Constraints', select 'Create' --> 'Primary Key'to define a primary key column.
2- View the data in excel like format
Browser view, right-click on your table --> select View/Edit Data --> All Rows
3- Add new row / Edit data
On the Data Output tab at the bottom of the table below the last row, there will be an empty row where you can enter new data in an excel-like manner. If you want to make updates you can also double click on any cell and change its value.
4- Save the changes
Click on the 'Save' button on the menu bar near the top of the data window.
I think some answers don't provide an answer to the original question, some of them insert records but with SQL statements and the OP clearly said WITHOUT, so I post the right answer: (Step by Step)
Alternatively you can use the query tool:
INSERT INTO public.table01(
name, age)
VALUES (?, ?);
use the lightning icon to execute.
You can do that without the SQL editor, but it's better to do this by queries.
Although, in pgAdmin, there is an option which you can click to have an excel-like window where you can add and update data in a table without using SQL language. Please select a table which you want to add a row first and click on the next icon here below.
Editing table data without primary key is forbidden
If your tables don't have a primary key or OIDs, you can view the data only.
Inserting new rows and changing existing rows isn't possible for the Edit Data tool without primary key.
Use INSERT:
INSERT INTO tablename (field1, field2) values ('value1', 2);
on pgAdmin 4, right-click on the table and use the item like below. You can also use that script in the background.
Finally, to watch the inserted data do like below. You can also use that script in the background.
All the above are correct answers. I just want to add that : When u create a table, make sure u have atleast one column as PRIMARY_KEY. Then, just follow the GUI : View/Edit data. U can add row as the last row of the table
As an update, the icon for the save button is different in pgAdmin 4.
This is how the menu should look after right-clicking on the table you want to insert into and hovering over "View/Edit Data".
After adding rows, either press F6 (on Ubuntu) or click the icon that looks like a stack of discs (database icon) with a lock on it.

What I would like is when one row of a table is updated and a new table that will duplicate the original table will update as well but the problem is the original table is a master table that depends on other tables. Any idea how to do this? I'm very new to postgresql.
This is what triggers are for, assuming that the source and destination tables are in the same DB. In this case I think you need an AFTER INSERT OR UPDATE OR DELETE trigger.
