Re: PgAdmin 4 : how to avoid error "Out of memory for query result"during SELECT with LOB ? - Mailing list pgadmin-support

Hi,

 

I set ON_DEMAND_RECORD_COUNT to 50, in the config.py file,  with restart of PgAdmin,

but I get same error “ERROR: out of memory for query result”.

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.

Hi,

 

I am running pgAdmin 4 version 4.15, with PostgreSQL 9.3 database,  and during SELECT on table with LOB (in TOAST), after near 5 minutes of wait I get error “Ouf of memory for query result”.

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
