Select count doesnt returns all rows in table - sql

Question

I do have a table in the database, which supposed to have more than 1k rows. The DB is Postgress. I use the following command:
select count(*) from icdten; it returns 1000 which is wrong
and also
select * from icdten;
returns the first 1000 rows, which is wrong I want to have all of them. Googling didnt find, or maybe I was googling the wrong thing.
EDIT1: I use PgAdmin, maybe it is PgAdmin issue.. I just did not find that option looking through the interface. It supposed to have 14k rows.

Answer 1

Possible limit is set in PgAdmin. Please look at Options/Query tab of PgAdmin like described in http://www.pgadmin.org/docs/1.4/options-tab3.html (http://www.pgadmin.org/docs/1.16/options-tab4.html for version 1.16 you mentioned):
Maximum rows to retrieve can be set to 1000 (default is 100, people usually change this value), and also "Count rows if estimated less than" may affect to COUNT function (it can use count from table statistics instead of real table count, so try to set temporary this value to a big number)

Answer 2

Here is how to troubleshoot this issue:
First try from psql. While select count(*) should give you the same on both, maybe there is something going on. Also there is no limit there, so you can:
\o testfile
\i select * from icdten
\q (exits psql)
wc -l testfile
If that still shows 1000 rows then you probably have 1000 rows in that table, start making sure you are connected to the right db, querying the table you think you are, etc.
EXPLAIN ANALYSE
May be helpful in that case.

Answer 3

This is not an error. It's simply a default parameter set in some versions of PostgreSQL.
You can change the parameter by going to the PostgreSQL's installation directory and navigating to pgAdmin 4\web. The directory for version 12 looks like this:
C:\Program Files\PostgreSQL\12\pgAdmin 4\web
Open config.py with a text editor and search for ON_DEMAND_RECORD_COUNT. It is initially set to 1000.
##########################################################################
# Number of records to fetch in one batch in query tool when query result
# set is large.
##########################################################################
ON_DEMAND_RECORD_COUNT = 1000
You can comment this line out but it could result in other errors. I would suggest to change it to a large value like 10,000,000. If you can't save the file after the modification you need to copy the file somewhere else, make the changes and save, then copy back to the original folder and replace with the original file.
