I’m sorry, here’s the formatted message text:
I'm running an ETL process that joins table1 with other tables (CSV files), one
table at time (for example table1 with table2, table1 with table3, and so on).
The join is written inside a PostgreSQL istance using JDBC.
The entire process runs successfully if I use table2, table3 and table4. If I
add table5, table6, table7, the process run successfully with table5, table6
and table7 but as soon as it reaches table2 it starts displaying a lot of
messagges like this:

With smaller datasets the entire process runs without any problem. What does
this mean and how can I solve the issue?
