Hi, You can run SET FETCH_COUNT 1 in pgAdmin query tool also, which will be applicable to that session only similar to psql.

For information, the result set contains 279 rows. When I use the LIMIT clause in the SELECT order, error raise near 150, but I do not test all values to find the edge. Thanks by advance for your help.

Adding LIMIT clause in SQL work well, but I want all the rows of the result set. I understand that with psql command I can use “\SET FETCH_COUNT 1” to avoid such error, but what to do with PgAdmin 4 ? You can limit the number of records to fetch in one batch by changing the ON_DEMAND_RECORD_COUNT variable in the config.py file. You can override this setting to the appropriate number (default is 1000) in the config_local.py or config_distro.py file. The details regarding configuration file is at https://www.pgadmin.org/docs/pgadmin4/4.17/config_py.html#config-py Thanks, Khushboo Thanks by advance.
