PgAdmin 4 : how to avoid error "Out of memory for query result" during SELECT with LOB ?

[STERBECQ Didier]

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 ?

Thanks by advance.
