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

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.
